First off, I’m a huge Sony fan despite anything contrary implied by the title of this post. In fact, I’m more excited for Sony’s PlayStation Vita (PSV) than for any other handheld game device ever. I fully plan on picking one up the day of release and playing until either my thumbs bleed on the awesome dual analog sticks or my wife starts threatening violence. Yet, despite my personal enthusiasm, I can’t ignore the fact that the PSV is entering a market vastly different—and dangerously more competitive—than the PlayStation Portable (PSP) entered in 2005.
Psp mainly sold well due to being hackable i reckon vita's games will sell better then psp games
I tend to agree with this author, it's also what analysts have been saying since the system announced. The system simply won't sell as well as the PSP. That doesn't mean it will be a failure though, there will always be a niche for dedicated gaming handhelds.
The system is not out yet, so no one can tell for sure.
The second things is, the Vita does a hell of a lot more than the PSP. I expect it to sell more and I also expect people to play it more than the PSP. It will sell well and at some point overtake the PSP. The games are what help a console sell and sometimes what the console can do for the player. The Vita has a lot of punch and a lot of software coming out.
When COD and If battlefield comes on the vita, they will push consoles. A lot more if you can play a game with your friends that are at home on their PS3. Cross Platform play.
