I think PSM is a failed idea from the start. The user base is too small, there is no good incentive for devs to go into this. People who want to target casual gamers should aim at iOS and android which both have dozens of times the user base of the Vita + playstation certified devices. Add to that the stupid limitations from the PSM (no open source, no free software), and you get an idea that was initially great (reduce android fragmentation by having certified devices) turned into a nightmare with a super small userbase.
People who target hardcore gamers will have better luck either with Minis, or by getting an actual real contract with Sony. And people who target casual gamer, as I said above, will crunch the numbers and logically go to iOS and Android.
I have a few US PSN codes to sell for a reasonable price (cheaper than pcgamesupply). PM me if interested, 1st come 1st serve basis..
