Remember that developer Double11? Don't feel too badly if you don't, because the studio popped up only last year in the UK, and they haven't been very forthcoming about their mystery project until today, when Sony revealed said project: LittleBigPlanet for the PlayStation Vita.
The studio was formed in 2010 by ex-Rockstar engineers Lee Hutchinson and Matt Shepcar, and they've been hiring like crazy while effectively keeping their involvement under wraps. Not that they're handling the handheld LittleBigPlanet game alone. Instead, Double11 is co-developing with Swedish developer Tarsier Studios, who has contributed "significant content" to the previous two LittleBigPlanet games on PS3.
