1-the most obvious reason -short battery life-1-3 hours on max settings,

2 price -- another good reason no one pays 250 for a handheld let alone 300 for 3g , unless they are die hard fan of sony and considering the psp userbase- not looking to good , so with that said thats the reason this is number 2

3 lack of interisting titles -- - uncharted asphalt and ridge racer seam to be all vita offering , and seeing as the 2 are on 3ds already , that leaves uncharted not counting countless ports of ps3 titles and i dont buy ports sorry , so that kinda debunks those

4- timing, they choose to hold their next handheld so far behind , they had an opertunity to announce it at e3 , and they did not they choose to wait more , and when they did they didnt even announce the spacifics for the us and still have not , , the only country that has confirmation is japan , , we always get the dead end of it , and its going to be so far behind by the time it comes 3ds will have alot of good games while it only has 3 mentioned above

5- price of games ---- -$59.99 for a handheld thats pretty bad, considering its not even nearly as powerful as sony promised to begin with ,

6 lies- -- - sony lied when they showed the product , the product they shown is actually more powerful then the one we are recieving , ----they did this obviously to fool those people into thinking it was gonna be on par with ps3 when in reality it is not

7 nintendo wii u is around the corner ,and may launch at a reasonable price - if that happens , this would definatelly kill any chance vita has , because why

its more powerful can do more, and unlike vita its not going to recieve countless stripped down ports of console titles instead itll have on par multiplats or exclusives that take off ,

8 --- monster hunter tri and monster hunter 4 are exclusive to the nintendo 3ds , as is mariokart 7 super mario land 3d luigis mansion paper mario kid icaris etc , -- when people look back at the 4 previous handhelds from nintendo they will know what 3ds future holds , games games games and more games i guarantee you by the end of the 3ds life span theres going to be 800 or more games available , most of which pretty decent , this was a problem for me as i am so far behind with ds i may end up behind again ,

9 backwards compatibility w psp is only possible if you rebuy your entire collection on the psn if your title is of course available , -this isnt a problem with the nintendo 3ds all ds dsi games are compatible plus now the 3ds has another thing vita dont- virtual console where you can download classic gameboy gameboy color nes soon game gear tg titles, i wouldnt be suprised if gba some how made its way - its coming for ambasadors for now but , we know nintendo theyll want more also snes titles can easily be made as well , -i would not mind that at all -zombies on the go would be awsome , 3ds has more oppertunity then vita does ,

10 the cost of development why its so low on this list cause it hardly had affected past consoles but it is worth noting it will cost more then a 3ds game to develope and for developers who cant really make big budget games vita would not be the suitable platform , until they do get on their feet , ,

that said ,

when i mean fail i mean fail to out sell 3ds not commercailly , so dont think itll fail virtualboy like or dreamcast like ,

it will be competitive enough to stay there , i dont think it will take 3ds away
