Looks like Apple shipped Logic Studio 8 and Logic Express 8.
- Some quick notes:
- price drop? – looks like Express is now $199 (I think it was $299 before), and studio seems lower than it was before.
- Soundtrack Pro 2 is now in Studio – this may be the single best new feature.
- Five of the Garageband Jam Packs are now included in Studio
- full ESX24 sampler in Express
- Some kind of performance mode in Studio
I’m personally curious to know what the educational pricing is (I qualify due to my day job) – Express for $99? We can only hope 
Update: looks like Academic Express is $179 and Academic Studio is $449.
