This is normal for Sony to do that because of the Xbox 360 Elite with it's 120GB. I think the PS3 should get at least 160GB just to make it bigger than the Xbox. But if they plan in offering HD movies/shows download later on, the bigger the better on the long run. But, because it uses a 2.5 inch SATA drive, it would cost more than any 3.5 inch drive.  I just hope they don't overcharge too much or people will think twice or go with an external drive.
