Machinarium comes to Vita in North America on March 26. The robo-stuffed point-and-clicker jumped from PC to PS3 back in October, when developer Amanita Design announced an upcoming Vita version, albeit with "no idea" when it would arrive. March 26 is a little more concrete, as is a price of $6.99 - cheaper than on PS3.
Amanita previously described the PS3 port as the "ultimate" version of Machinarium, so we're not sure what that makes the further tweaked Vita version. In addition to the PS3 enhancements, Amanita says the Vita version employs both front and rear touch controls, and brings improvements to the zoom feature.
