don't worry, For all you XBox Fans, Next Gen Xboxs might steer you into a walled in corner.
Hear they are talking and considering making a DRM or whatever, that essentially will break used xbox games. Where the game will be Tied to the serial of the xbox, if you pop the disc into another console, it won't work, if you break your console, you'll have to buy new games (Haven't heard them say on how they will combat this). Etc
PS3 Can be a quick one-all that is rather cheap and capable. But a Good Desktop pc (especially right now) can come along for almost as cheap, and hold its own in the battle. If you do-it yourself/build it yourself with or without a barebones kit, you can get a computer that STILL stomps Consoles into china or even further thru the planet and out the atmosphere.
As a quick reference. I spent 300$ swapping only a few parts from an OLD (3-4+ year) computer(which I'm fairly certain we upgraded from an older computer back before). I also now own Skyrim for PS3, and PC.
Everyone should already know, Mods/ user created content is something that pops up ever day on PC, Skyrim is no exception, they even have a creation kit, But Loading screens, are almost non-existent. Where as on the PS3, I'm sitting at load screens for a good 2-3 items/characters worth of discussion
Also, A very capable computer, should be able to utilize the 'custom-made' Snes, Gba, Nes, sega, n64, psone, ps2, ps3, xbox, and xbox 360 emulators..... not sure if a wii one was ever though of.. pretty sure theres a gamecube one. Probably one for the other console/handhelds. Though some mechanics may still be singled to the consoles themselves
PC's can get Blu-ray Players, They also have a higher resolution max than "1080P", while they may no longer be the only one, consoles still don't have that quality.
