I think Sony purposely keeps some of these PSP titles from being officially supported to keep people interested in new PSV titles. I have Mod Nation Racers on the PSP (got it for free but never played it--thanks, PSN outage!) but they released MNR: Road Trip. The PSP game could cannibalize the Vita game so I bet they figured it was a smart move to hold it back for a while.
Same goes for the Metal Gear titles or Resistance Retribution.
