Yeah, it really does seem impressive, especially the AI and overheat.
AI no longer be able to dive past the dive limits, only been asking for that for about 9 years!!!!
Anyway, it will lead to some sort of decision to be made.
Obviously no one knows how much changes to existing classfiles have been made yet, but they will not be rewriting UP3 to go over 4.11, thats for sure.
UP3 may however reap some of the benefits, as its much easier to take for example the 4.11 AI code and put it into 4.10.1 than make all of the 4.10.1 mods fit 4.11, and they 'may' cherry pick the best stuff out.
From a personal point of view, i'll be keeping a clean 4.101, clean 4.11 and a UP3, and probably a modded 4.11 for eye candy and sounds.
If they could only all pull in the same direction, what a game!
