I haven't got a PPC so it's not up to me to decide.
But if it was me, i wouldn't do a Blizzard version. I even think they should not have done a Cyberstorm version.
Why? As Skipp604 says, we need a new start. A new modern OS supporting new modern hardware. The old Amigas have been hacked, mutilated and are having expansions sticking out of every possible hole. I think the end is reached there.
I do have a lot of respect for PPC card owners because they took a big risk to support the Amiga platform (even thought about buying one myself to watch demos). But these cards are, one have to admit, a hack, something that will never have optimal performance.
OS4 + new modern PPC hardware. That is the only solution to have a future. The rest is history...
