So the PS Vita is now all but revealed, with "official" Sony posters leaked. Of course this is all just speculation but with NGP (Next Generation Portable) just a concept name, like Project Natal, Vita does sound all the more appealing. With Sony usually going for bland names like the numbered PlayStation console series (1,2 & 3) and the original portable PlayStation being named, well, PlayStation Portable, I personally believe that they'll go for a more original name. My money's on it not being named PSP2 but instead on it being named something with more of a kick, how does Vita sound :P
For another thing I also believe that they would not hinder the specs unless they had to, but then again I believe price point will make a big difference in whether or not it sells well. With the 3DS not selling well because of the potential health risks (http://tinyurl.com/3h3goon) I think Sony's purely tech filled selling point will excite gamers not otherwise enticed by the handheld markets usually graphically poor games.
