In a recent interview with Digital Trends, PlayStation All-Stars Battle Royale director Omar Kendall hinted that a Vita version may be in the works.
At the end of the interview Kendall was asked directly if there was a “chance that we might see [All-Stars Battle Royale] on Vita”, to which he replied “Maybe… Stay tuned.”
While his answer wasn’t exactly a confirmation, it was about as official as an unofficial announcement can get, plus it makes sense considering the Vita desperately needs software to boost consumer demand. My guess is that we will see a PlayStation All-Stars Battle Royale Vita version announced at E3 next month.
