Silent Hill on PSP and Collected

I noticed some rumors leading mostly to 1UP, that there'll be Silent Hill on Sony's Playstation Portable (PSP). If so it can be previously mentioned Silent Hill 1 Rerelease.

I also have something to update my later Silent Hill Collection info. Several sites states 13th April as release date (in contrary to 28th I sought on several on-line shops). Some messages on the Collection also declare Silent Hill 2: Restless Dreams to be in. I don't have much relevant to support these.
