This list of games to be released in 2014 says it all........... http://www.ign.com/articles/2014/01/16/the-top-30-playstation-vita-games-of-2014
Here are a few things you must look at,
(1) 2013 was a very VERY solid year of releases for the Vita. Killzone, Dragons Crown, Guacamelee, Y's, The Walking Dead, Soul Sacrifice, Tearaway, Sly Cooper led the way in some of the best portable games released last year.
(2) 2013 Also saw many Indie titles released on the Vita. Lone Survivor, Spelunky, Terreria, Hotline Miami, are just a few.
(3) The Indie game development is on the up and up and as you saw with Sony's pledge to support these games, you will see many more great Indie titles come to the Vita.
(4) Digital sales account for most of the Vita's sales, so even if you may not see them chart on the monthly NPD sales charts, just take a look at the PSN monthly sales charts. Vita games are selling well. Add to that all the PS+ DLC sales and you have digital sales that are for the most part in the dark.
Sony however needs to do a few things to see the Vita sales pick up.
(1) Drop the price of the memory cards to a reasonable price. ($20 lower that they are currently) would be perfect.
(2) Bundle the Vita with the PS4 ASAP. Lets face it, the PS4's demand is currently through the roof and sought after by by millions of gamer's around the globe. a PS4+Vita bundle priced at $550 would be gold...... Keep on Gaming.
