I'm not sure if this has been posted yet, but I noticed it in the comments section of one of the EU Playstation Blog threads. The quote is from a Sony rep about the cross-buy system:
"It applies to both. If you purchase either a physical or digital version of an applicable PS3 title, you can download the Vita version at no extra cost."
I was planning on buying all those games physically anyway, so I'm basically being given a free Vita copy. Insane...
