Saw this at GameSpot while looking for information about Kingdom Hearts: Chain of Memories, and saw a preview for Lego Star Wars, for the PS2.
Yes, that's right. It's a PS2 game, based on the LEGO Star Wars sets. It's scheduled to be released in April of 2005, for the PC, PS2, X-Box, and Game Boy Advance.
I really have nothing more to say, other than this sounds like a really, really strange idea.
