Rockstar? Not for their games, but only because they one of few developers who actively provoke people with their games.
Capcom? I don't really know, though I guess so. They don't make a lot of games I have any interest in.
Developers I would feel sad about losing would be Criterion Games and ArenaNet. They make great games and they give them great support, and in general, developers could learn a bit from the ways these two developers have done things.
