Multiple Questions for NGP PSP?

Hi guys, I just want to ask a question about the NGP PSP, for the NGP PSP, will it be able to play UMD games because I don’t mind downloaded games but I know that downloaded games take a lot of memory so that’s why and does the NGP PSP use a memory stick or is the memory built in because I think the memory stick would be better, not a built in one. Another thing is, is it coming out in 2012 January 1st or some other day, please state thanks. Another thing is I see many people on the internet saying will it blend, what do they mean by that. Also in this video http://www.youtube.com/watch?v=WOg_84DuSBw 2:14-2:28 it talks about the Playstation suite and how it is connected to the android phone or something, how about if you have a blackberry, than what. And one more thing, will they stop making UMD’s after they release the NGP PSP and make it all PSN. Please help. Thanks soo much.
