The thing is corporations do not go where the ideas are, they follow the money. If they are leaning towards casual games it's because it is selling.
Sure. But "casual" games is a different market altogether. The reason casual games are so (relatively) successful is for the same reason the AAA 6-months-or-newer-hardware PC games market is failing miserably. That more people are realizing that smaller teams can make just as much money making simple yet enjoyable 2D color matching games, as they can making boring repetitive formulaic FPS and at a fraction of the cost, is great news (for the consumer, although not so much for the aspiring developer)!
