Just as the title say's would I be able to upgrade to Leopard when it comes out? I was wondering this because I would like to have it on my G4 PB when it comes out in October. I hope Apple Inc., doesn't screw me and force me to upgrade to their intel macs anytime soon. But I do plan to upgrade to a iMac next year I hope to do that soon. I already have a 64 bit processor which core64 is running on 10.5. I think i would have to bump up my ram to 1.25gb instead of 768mb of ram. Any help on system requirements for Leopard would be great.
