Comparing PS Vita to PSP is essentially of no use as the Playstation brand went from being the most popular to falling from grace in the time between PSP's launch and PS Vita's launch. PS3 & PSP launched well as Playstation was strong, it's still strong but nowhere near as strong as it was; PS Vita sales show this and they are expected.
All in all, a mediocre launch.
In perspective even after these Vita numbers I still feel 3DS had a more disappointing launch considering its predecessors popularity and the increase in Nintendo's brand power between the time of Ds launch to 3DS launch.
