Sony has said that the sales figures for digital download versions of Vita software are "exceeding expectations".
As reported earlier, PlayStation Vita's 20 launch games sold a combined total of 300,000 copies in the system's first two days of availability, according to Japanese retail tracker Media Create.
That compares unfavourably to the 0.95 first week attach rate of 3DS and the 1.06 first week attach rate of PSP, but that does not take in account the games Vita owners have purchased digitally via PSN.
Speaking at a press conference for Gung Ho Entertainment's Ragnarok Odyssey in Japan this week, Sony Computer Entertainment Japan CEO Hiroshi Kawano said the retail sales were "a figure in accordance with expectations".
But he went on to add: "Sales of the download versions of titles are exceeding expectations," and that games and peripherals are selling extremely well."
Kawano refrained from revealing any hint of the download figures.
