Sony would like the PlayStation Vita to have sold more units, but admits the software isn't up to standard yet.
"We would love it to be selling more and we intend to make it sell more and help it sell a lot more," Sony Computer Entertainment UK boss Fergal Gara told MCV UK.
"I think we haven't quite hit the spot with the killer software just yet and I have every reason to think that will happen in the next few months.
"The key thing for the rest of the year is the key software drive for the console so as we look towards September, LittleBigPlanet, that really is taking the concept on another level because of the Vita functionality.
"And of course the other key big third party IPs - Call of Duty, FIFA, Assassin's Creed - will do tremendous things for the Vita. So it's our job now to take that strength of software and give people more reasons to buy."
Combined, the PS Vita and PSP sold less in the last quarter than the PSP alone during the same period in 2011.
