Apologies if this has already been posted, but I spotted on the Blizzard Tech Support forum that some Blizzard games will not be supported under Lion. They will still be fine in Bootcamp or Snow Leopard.

This summer, Apple is scheduled to release Mac OS X 10.7, Lion. Due to advances in Mac operating systems, StarCraft, StarCraft: Broodwar, Diablo II and Diablo II: Lord of Destruction will not run on 10.7.
While these titles will not be able to run natively in 10.7, they should still be able to operate under Boot Camp. And of course, we will still support these titles running in 10.6 and below natively.
At this time, we expect Warcraft III to run natively in Mac OS X 10.7.
As Lion's release date gets closer, we look forward to having more details for our Mac community.
For more information about Mac OS X 10.7 Lion, please see Apple's website:
