^^ I don't think that video exists... They may have said that the NA motor would be around for as long as possible but don't believe that they said such a specific statement.

It exists. Go look for it. The Rennlister that was at the PCA meeting has reported this several times and the AP comment is on youtube - I believe it was an interview with Henry Catchpole. The reality is AP and Walliser are not decision makers and as such you can't rely on their commentary or viewpoint. Decisions change, based on corporate objectives and the regulatory landscapes the cars are sold into.
From my perspective it makes no difference, as I have my bases covered (deposit down on 992 GT3).
On the one hand we have seen a Spyder that appears to be turbocharged and we have seen what appears to be part of an engine production schedule that has a 390PS 2.5l turbocharged H4 on the list - the 4l GT3 and 992 engines are on the same list. On the other hand there are statements made by GT Dept people that the GT4 will be NA, the Spyder will be NA and there is no plan to produce a GT4 RS.
I'm not particularly excited by what I'm seeing - the physical evidence appears to outweigh the verbal evidence. By the same token, we will know the actuality when the car itself is revealed.
The modelled performance of the 2.5l single turbo, H4 will satisfy some and disappoint many, if indeed, that proves to be the outcome.
From 981 -> 718 all the Caymans went up 25HP. I don't think it's likely that the 718 GT4 will be rated at the same power as the 981 GT4 @ 385HP.
It's an interesting list that makes you wonder how many of these will ever see the light of day in a real car. There's a 2.0 H4 with a 20 PS increase in there, and also a 3.0 H6 with 500 PS. What would they possibly use those for?
This list was discussed on rennteam.com as well. They noted that there is three 718's listed... Base, S, and GTS. The list does not include the Spyder or GT4 yet. They also noted that in typical Porsche fashion, HP dyno ratings are higher than the marketing department claims.

The list has two power variants of the 2.0 engine for the base car so I guess the most logical conclusion is that one is current and the other is for next gen. The 2.5 is seen with 350, 365, 370 and 390 PS which represents exactly 20PS over the current model in each case except that the highest number would be 25 over the current GTS.

I don't think this is the case with the turbo engines based on testing I've seen done on MAHA dynos. What happens is that the HP gets inflated by the dyno correction factor whenever conditions are worse than standard (which is most of the time) because the engine's ECU is already compensating to maintain the same actual power output in all conditions from the desert in Dubai to a mountain road in the Alps. When you then apply a correction factor to it as if the engine is not already compensating you get a wrong number. Only for the NA engines are dyno corrections appropriate.

Exactement - and there is a full technical paper on this exact issue (in fact Porsche were involved with MAHA and Sport Auto to ensure the facts were put out there).
Note the presence of the 9A1 G Series engine and the new 9A14l along with the 9A2 718GTS correctly identified in the list.
For the 390PS engine the redline may be the tell tale ~ 7750RPM and in that line of Caymans and Boxsters - its unique.............
Also its worth noting the 992 Series I engines have been identified - e.g. (991C 370) 400PS, (991 CS 420) 440PS and (991 CGTS 450) 470PS.
and perhaps even more interesting, do we have the new 992GT3 identified......500PS and 550NM and another point to note, is the RPM number a value for peak HP in which case 500PS, 550NM and 8400RPM redline.........(at least for the 911s).

Looking at the current 4.0 engine, the RPM does appear to refer to peak power. Peak power at 7400 means redline probably no higher than 8K more likely a bit below.
I'm slightly sceptical about it being for the GT3 though given that it would be the first time ever they don't bump the peak power number on a new GT. We know that a 500HP turbocharged Porsche is faster than a 500HP NA one (all else being equal) but I would expect at least a 20-25 HP increase over 991.2 for marketing sake. And they've been consistently firm that 992 GT3 (certainly 992.1) should stay NA, unlike GT4 about which they've said just about nothing at all. What they would use a 500 HP 3.0 for though I have no idea. Seems too much for the next GTS.
I just noticed the first couple of 9A2 engines are for 981 in that list, so not the most accurate in the description department.
I also noticed now that, while taking it with a pinch of salt due to somewhat old spreadsheet, forecast production numbers for the 390PS 2.5L is zero all the way to Q1 '19. Same for all the other power-bumped H4 units that cover the base, S and GTS.
It does forecast the 390 and 440HP 3.0 H6 engines to start getting built/delivered from Q3 '18 onwards as we would expect from 992.
So maybe whatever 982 GT4 will have is simply not on this old list.
