I have so many better things to Spend $1000 on, though. I think my girlfriend would resent the fact that I spent $1000 on game consoles -- not even the games themselves -- so I'd actually have to have $2000 in spending money to treat her too.
I'll probably eventually get all three, but not until prices come way down. I didn't buy a GC or PS2 until they were $150 (and the PS2 I got used so it was $120 anyway), and maybe I'll get an XBox soon for $100 or so.
I'll probably be getting the PS3 for obvious reasons, which is now straining my plans -- saving for E3 and a PS2 -- but the Revolution is what I'm really looking forward to.
