If they were to remake it then I'm positive that Sony would pull out all the stops to ensure it came to the PS3. It would move a lot of consoles, over a million maybe. I'd consider getting one if it did happen (although definately not at the current price).
However I think it highly unlikely it will happen. I'm sure it will get remade, just notfor a good number of years yet. The original still stands up rather well I think so there is no need.
