1. On GTE Pro, I think in a recent interview Walliser pretty much confirmed that the new car will be 911 based, like it or not. Still, I entirely agree with your points above.

2. On LMP1, I have just read an article in SA on future rule changes and EoT:

 ° In essence, the 2018 rules are likely to move further towards emphasizing higher classes of hybrid power (up to 12 MJ versus up to 8 MJ now) and deemphasizing the role of the combustion engine through further fuel cutbacks.

° The next rules change after that in 2021 could include fuel cell technology for the first time, spawning a fuel cell EV racing car; that is what BMW seems to be aiming at for strategic reasons. (Where is Merc on that, given their longstanding research into fuel cell tech...??)   

Given Porsche's Mission E project, the corporate strategy behind it and its timing in 2019/20, if VW Group/Porsche were to make progress on fuel cell tech as well, this could be exciting both on and off track...
