Hmm. From your post, it seems you like the complexity of PC games but let me just say that games are meant to be fun. Simple concept. Some games made on the PC are more fun because of its complexity but from my experience, most aren't. You used Ghost Recon and Rainbow Six as an example. I can tell you that I enjoy RSV very much due to it being more simplistic but I hate GRAW so damn much and that was built separately for the PC. I would have prefer the 360's version of GRAW instead. I'm spending most of time in GRAW ducking, find cover, and persistently looking around for enemies, dying, and starting over again. It's just not that fun.
Secondly, PC gamers get a lot of exclusives because of its unique interface from consoles. There's no lack of complex games on the PC right now. (Of course, people might have different definitions of complexity.) Those games aren't going anywhere. For every developer who decides to switch to console development, there will be another one who decides to concentrate on PC development only.
Thirdly, not all PC exclusive games are complex. A huge majority of them are casual with simple controls and they are fun towards the people they're being market to. There's no harm in that. The gaming industry is big enough to account for all types of gamers. There's no need to start point the finger towards certain groups just because a few franchises you love are no longer what they used to be. Things change. You can usually find new games to play that fit your needs.
