Did you read on REAL Software's blog?
Even if REAL Studio will no longer support PowerPC, we can't simply follow. We have a lot of users who stay up to date with plugins, but use older REAL Studio versions. For us, it's more a question how long Apple provides us with development tools for older platforms. We removed Mac OS X 10.3 support only because Apple's developer tools have no way to run 10.6 and compile for 10.3. And we need to use the latest system to make plugins using the newest features.
So our PPC Support could end with 10.7 if Apple decides to remove PPC support for their compilers.
