i would hope nobody was under the mistaken impression that vita (or 3ds outside japan) software is selling anywhere near acceptable numbers.
the only remarkable thing is that wiiU stuff is selling even worse.
Wait. Outside of Nintendo titles, I remember titles like Sonic, Skylanders, Tales of and Lego titles doing decent / well. At least in US. creamsugar posted both Vita and 3DS US top 20 up to June and 3DS showed generally not so bad software sales, with just Resident Evil: Revelations shining as the biggest flop by far.
And in the Vita list, Marvel v.s. Capcom shined as a game that didn't do as bad as everyone expected ( over 100k)
