This new venture has no promise. Seriously who the fuck cares if baldurs gate is released for a new platform. The game is played on pc and can be played on mac if given an emulator. There is no reason anyone wants to play it on an ipad because your almost completely better off playing on a pc laptop.
1 new adventure/1 new npc?
Are you joking, if they were to do anything about the game, start with the engine. They would take it to the icewind dale 2 engine so that feats can be used, therefore giving more replayability. Other than that, there's not much they can do to make this game any different. Such a waste of time
I can give you a reason why play it on an Ipad, I work 5 days a week 15 hours a day on the road as a concert backline for a sound company. so I get 2 days to play on my pc. When I'm on the job i sometimes get 3 to 5 hours of break in a row but no way to get back home to play because I'm hours away from home. Even if it's the same game with no upgrades I'm planning on buying it for my Ipad.
And for the engine upgrade if there's one thing that would hold me off on buying the game for an Ipad completely (besides DRM) is to see the BG games on any D&D ruleset that is not the 2d that it was first made on 1998. So for your idea to implement 3.5 rules for BG is one of the worst ideas, just watch how many people like IWD 1 over the 2.
