I've posted this, or atleast something similar in another forum, and the recent no sports games on the 3DS got me thinking maybe it'd do good here. No basketball on the Vita either though there is a PSP game you can purchase digitally and play on the Vita.

As a Playstation fan, the biggest problem with the Vita is that most games are multiconsole with the PS3. Games like Dragon's Crown, Ninja Gaiden Sigma, etc. Sony themselves have no interest to do anything about this as they're mostly interested in rushed ports rather than getting exclusives on the system and the system isn't exactly a money maker in the west so most Japanese games stay in Japan, and the western devs have all but forgotten the system.

If you own a 360, there's less of a reason to purchase the Vita, but there are still going to be more games you can't play than if you were to own a Sony console. The real value from the Vita comes from those who don't own consoles at all or those who are Nintendo only. For those that don't own consoles or own a Wii U and 3DS, just about every game on the Vita will be new for you, and so long as you're not a PC gamer, the indie library will be mostly unique as well. The system might be full of ports, but it doesn't matter when none of those ports are available to you. Additionally, for everyone who hasn't owned Sony consoles, you have a back catalog of great PSP and PSX games as well.

The Vita does have remote play for use with the PS4, and if you own a PS4 but not a PS3, then everything is still new. Not sure how you can market the game to tell non Sony gamers that this is the portable for you, but that's what Sony should have been doing if they weren't going to make a system for their own fanbase.
