Groove Agent 4 announcement

I prefer the sliders in Groove Agent 3, allowing us to get a groove going without thinking about programming at all. The whole point is to not do any drum programming, because I’m a guitarist.
Can we use Groove Agent 3 in Cubase 7.5? I have a lot of projects that were started with GA3. Can I still open those up if I move to Cubase 7.5 from6.5?
