Buy a cheap PS3. Saving for a system you have no idea about that might somewhat fail or might have manufacturing faults etc (like yellow light of death/red ring of death) well lets say there is smarter moves.
You will also most likely have an insufficient number of games. Wait at least 6 months when the system is out you have more games and you might even save 100 bucks because the retailers start the price war.
I bought my second PS3 1 month ago and got it for 115 (including move camera and controller) so when you are lucky you should be able to get one for cheap (you can even buy imported once since the PS3 is region free).
I bought my first PS3 years after the console came out and immediatly had 40+ games that interested me and most of them were total bargains so.
Best decision I could have made.
