When we heard about Blu-ray-to-PSP movie transfers getting all official we got pretty excited, even though the announcement was a little skimpy on the details: How big are the files? How long will it take to download a movie? How odious is the DRM? Most importantly, when? Well, we've got 'em all right here.

The deets: The movies are around 1GB (standard def and PSP-optimized) and take about 3-5 minutes to download via USB to the Memory Stick Duo in your PSP. Currently, the idea is that they aren't stored locally on your PS3. Sony expects it to be available sometime this year—nothing more fine-grained than that timewise, unfortunately

The sweet news: For now, the plan is that the service will be free and it "can be used potentially on any Blu-ray movie title." Hopefully that means it'll be available for every Blu-ray title.

The potentially bleh news: Sony is still in the processing of reviewing how the DRM is going to work, and how portable the copies are going to be (important, since they're stored on Mem. Stick Duos, which are pretty pocketable.) In particular, the number of copies you can make from each disc is still up in the air—so it looks like how many friends you can share with is definitely going to be limited.

DRM-wise it's nothing unexpected—given Blu-ray's emphasis on strong copy protection, Sony's obviously not going to give free reign with the PSP copies. But even with some limits placed on the service, it stands to be one of the best PS3-PSP connections yet.
