I liked Lego Star Wars, but I wouldn't mind seeing it with the graphic stylings of Episode 3.
I own an Xbox 360 now. No more PS2
I'm a Sony guy personally, but it's all good. The beauty of it is that ROTS was released for both Xbox and PS2. I think they could make the whole anthology (including a jazzing up of the ROTS graphics) and release it on both Xbox 360 & PS3. They could easily put all 6 episodes on 1 disk (HDDVD for XBox360, and Blue Ray for PS3).
I do not own a PS3 yet, but if this game were to be made I would actually have to go buy one. Right now I'm just waiting for the price to go down. I figure around 2017 I'll buy a PS3.
