I'm not sure if this is supposed to be serious, but I'll respond as if it is ...
I think most people will acknowledge that the 3DS has a massive lead and will probably outsell the PS-Vita by a substantial margin until Sony cuts the price of the vita. Third party publishers have (probably) estimated the market through the end of 2013 and may expect the 3DS to be selling substantially more software than the PS-Vita simply because of how much larger the userbase will be, and they will have allocated their resources towards projects to maximize their sales (effectively meaning they will be targeting the 3DS). The combination of lower price, larger library, less expensive games, and greater third party support will make it nearly impossible for the PS-Vita to consistently outsell the 3DS; and the massive userbase and (likely) regularly higher sales will prevent the PS-Vita from getting much closer to the 3DS than they already are.
