Preview testers of Apple’s next operating system, Mac OS X 10.7 (a.k.a. Lion), have confirmed that Rosetta has been removed. This means it is likely that only applications have been written as Universal or Intel-only will run under 10.7. It has also been reported that Lion will not run on older Intel-based Macs that don’t support 64-bit (specifically all Macs with Core Duo or Core Solo processors can’t run 10.7).
