I can think of 7 people i know who have no fast internet access, yet have PS2s.  They wont be overly happy with trying to download a 500Mb demo over dial-up.

Add to that people with bandwidth limitations on the connection, and you have yet more people pissed at sony

The UK version is still going on.

Yep, even with the normal of 1mb or 2mb most people have 500mb still takes a while.
