Vita PlayStation Plus users getting Knytt, Big Sky and Mortal Kombat in December

Well, that honeymoon didn't last long. Sony will offer a couple of indie games and Mortal Kombat (which does rock) for the Vita via PS Plus next month plus some other reduced price content. That's a bit of a comedown from the blockbuster opening, and if Sony is resorting to throwing all the new games on the store to PS+ owners, won't that reduce the income developers get?

12th December: Big Sky Infinity (PS Vita and PS3)
19th December: Mortal Kombat (PS Vita)
21st December: Knytt Underground (PS Vita and PS3)
