You can now Purchase a 250 GB PS3 Slim for $349.99 USA retail and you can get a 120GB console for only 299.99 dated May 2010
40gb, 60gb, 80gb, 120gb, 250gb, also can be upgraded to 320gb at sony centers.
You don't. The 40 GB PS3 is not one of the PS3 models with Backward Compatibility. Sony claims that there is not anything you can do to allow it to play PS2 games. see related link
ps3 80 gb.
Yes.
No an update to the software would not allow it to play PS2 games according to Sony and neither would a change to the hardware
ofcouse!
no
it cost $400.
Well on websites and on the PS3 box itself it says no but when sony slashed the cost of the ps3 the 40gb onwards was not region locked to save money so yes you can play region 1,3,4 games on region 2 ps3 (unless its 60gb)
More memory, that's all.
No it can not
Yes.
