To me, PSN is still in its baby phase and has a lot of growing to do. I think Sony agrees with me. As of now, PSN is only available on the PS3 and the PSP. Blog news has it that Sony is looking to implement PSN into other hardware devices. Sort of being all speculation at the moment, one could guess that we could see PSN in TV’s, DVR’s, and cell phones. That’s all provided that PSN expands its media options as well. While all this sounds like it could be cool, nothing has been officially confirmed so we’ll have to wait and see.
