Oh yeah I totally trust them to deliver, too. If they go the same route as D:OS2 and only release say the first act until full release, that'll probably be the best approach. Gives a solid taste of the game without allowing people to burn out TOO much. The games that tend to release a start to finish experience, then add all the fluff and filler while they work towards release are usually the ones I can't stand, but Larian seems to be pretty good at this whole EA thing. There aren't many studios I give that kind of credit, but Larian has really earned it.
