I really wonder if being a "fanboy" to a console is fading, but to game types etc is picking up steam. There are those that really dispise Madden and wouldn't play any game with that name on it. There are those that love GTA, and would buy a disc with GTA 2 on it as long as it was titled GTA 4.
I'm a gamer. I've owned most systems going back to the NES. I don't always own them while they are new, but at some point I'll usually pick them up. What I've found is that every system usually has a reason or 2 to own them, if nothing else. Even the Atari Jaguar, which was a disaster by most measures, still had the wonderful Tempest 2000.
I own a Wii and a 360 right now, and I love them. Right now, I don't see the games that I want to play to fork the money over for a PS3. MGS4 will be the first game on it that I truely miss (and I can't wait until I eventually get one in a few years to get to play it).
