From everything I have read you can just pop in a Singstar PS2 disc in the PS3 (assuming you have backwards compatibility) and play it without any problems. They do use the same mics after all. I am still waiting to hear about wireless mics.

 

I've got the 80 gig so BC is no issue but is gameplay the same between the two?  In other words, is it essentially identical in terms of actual game features?

I don't think there is a lot of difference. Just make sure the songs you are after aren't already on the SingStore, or I would say you wasted your money :P
