A lot has been changed already, Some space was already saved by the time they released the PS3 in Europe without the full hardware backward compatibility of the PS2.... now that the other PS2 chip is gone too that's something.... also there are a number of ports and such that never even made it to the first PS3s, but they had already been designed into the current shell, so there is a decent bit of space inside a PS3 you buy today.
Of course it isn't going to be anything like the sexy PS2 slim... but it might be shrunk to something similar to the original PS2 size.
