well, apparently, it still has wifi and a hard drive. I can't see what else they would remove as far as features are concerned. Maybe no USB? But then no way to charge the controllers. Who knows, really.
No USB? How the hell am I suppose to connect my PS Eye for Move??
But yeah, they must remove something as you said to get the price down $100.
This is going away from the topic but the PS3 is 5yr old tech, it should cost $200 anyway..or it would if it was a PC..but it isn't I suppose.
I don't know why console depreciation is so much slower than a PC's when basically there are the same thing, plastic and chips apart from there isn't a newer console every month...maybe that's it.
