That would seem to be the death knell of PS3 hacking. It's a pity that Sony insists that such powerful hardware be limited to playing video games.

And I don't actually remember a great deal of talk about a Playstation 3 port.
I do remember bringing up the Cell processor. I also remember dropping the idea when it became apparent that IBM wasn't interested in supporting any applications it hadn't reviewed and approved.
As to MorphOS ports, personally I'd love to see ports to anything that featured a PPC processor, but realistically there's only so much that a small team of developers can do (especially if they want to do it well).

Frankly, I've just settled for waiting for the Powermac port (I've got the hardware at home and I'm waiting patiently). If a Powerbook port eventually occurs that would be great. Portable MorphOS!
