Apple updating the Power Mac G5 next week?

Alright, we know that Tiger is coming on April 29th, but Think Secret thinks that the rock won't stop there—they seem fairly sure that at next week's NAB conference Apple is going to introduce updated versions of the Power Mac G5 running on the latest version of OS X that may or may not sport IBM's new dual-core 970MP processor. They report that there is also some whispering that Apple might load up the new G5s with Blu-ray drives. Um, you know how Apple loves to be the first to market with these things (they were the first to ship a computer with a DVD recorder), but it seems way too early for Blu-ray to start showing up in desktops. Not that we wouldn't love to be wrong.
