I think it's wise to wait, at least for me anyway. I need some more information.
Now that I think about it, what's the point in buying one of these systems if you already have a PC? Aren't these next-gen systems now using x86 architecture? Seems to me these developers could easily make their games for all 3 now.
There's a few reasons for me. The primary is you buy a console and it's capable of running the games you buy at the highest performance for the next 7+ years. A PC requires graphic card, RAM, and processor upgrades which can cost upwards of $1,000 over that span. I don't disrespect PC gaming, but I don't want to buy a PC and have a game on it chug along 2 years later at a low framerate and less resolution because the system is already outdated.
Also I have a lot of gamer friends, 99% of them are console gamers. If I made the switch to PC I really would only have a small handful of guys to play with opposed to the guys I play with on a daily basis being strict console gamers.
I've been console loyal since the atari, went through a NES, SNES, Genesis, N64, 3DO, Sega CD, Gamecube, PS, PS2, Dreamcast, Xbox, and now Xbox 360. It's what I grew up on and have stuck with along the way. I'm sure others feel the same about PC and have been down the same path throughout their gaming life also. It's just personal preference.
