Well, Sony just delayed the Bu-Ray stand-alone players to August. So, I would assume they would delay the PS3 as well. Otherwise, they would kill one of their own product lines ($1,000 for stand-alone vs $600 for PS3). Links at:

Of course, these articles only talk about the stand-alone players. However, if they are having problems significant enough that they are letting Samsung beat them to market, one can safely postulate that the PS3 will be delayed as well.
