Actually, it has been confirmed since before E3 2005...it was never in the cards for PS1 and PS2 imports to be playable on the PS3...when the PS3 was first announced to be "region-less", it was made clear that it was only PS3 games. Only rumor and speculation even brought the PS1 and PS2 import scene into the equation.
As of Oct 19th, it's still a no.
