I think it will be a very very good strategy if PS3 is compatible with all kinds of HDs.weaksauce said:
I am sure that if the PS2 was compatible with various HDs for various uses many (if not most) PS2 owners would have attached one to their console and bought FF9 afterwards since they could play it.
Buying an expensive HD that could be used only on PS2 only to play FF9 was a bad idea for the consumer.
