I've sat back and read all the hating of the Sony and PS-Vita threads listed here, and the only conclusion i can come to, as for the reason for all the hate is either, it's a bunch of jealous 3DS owners who already sank there money into the gimmicky 3DS sinking ship, only to discover the monster hardware that is built into Vita......or
It's a bunch of PC and console gamers that just flat out hate portables and will say and make up anything to try and deter gamers from buying and enjoying the latest and greatest portable that is finally equal to current gen consoles.
Either way your hateful remarks and failing predictions will be proven wrong in 1 years time when Vita's hardware and software sales increase far beyond 3DS could ever hope to obtain, so save your hate and failing speculations that aren't based on any real facts or analysis, since the system has yet to release here in the U.S.
It's way to early to predict any hardware sales failures, especially before it officially launches.
The 3DS, however, did release with stagnent numbers and loss ground from there, the only reason they started selling more recently was because of the Nintendo's 1st party releases, once those sales die down, so will the sales of the 3DS, as usual.
Sony has always had better 3rd party support than Nintendo and they will again thanks to Vita's capability of being able to get direct ports of console titles.
