Apple updating the Power Mac G5 next week?

So, the gossip is that the new G5 Powermacs will support the dual Core CPU (the 970MP) - which would explain why these are being released at the same time as Tiger - what's the point in a new CPU unless the OS knows how to use it? The gossip also is that the new Powermacs will be shipping with Bluray drives.

Now, that would be impressive.
