I feel like the PSP already gets plenty of ports from the DS and the app store I only think the trend would continue. It will only be easier sell this time around as the systems are more similar in specification so it's less work than before and the trackpad on the back would probably help ease the transition from touchscreen controls. As companies like Atlus show It's a great way for smaller publishers japanese and western to get a little more profit from their initial investment.
In short I concur. I honestly see the 3DS and PSP2 being much more like the PS3 and 360 than the landslide of the DS vs PSP. Mostly similar third party library with the exception of 1st party titles which of course for the masses will lean in Nintendo's favor but neither being considered a big loser(lest they are constantly compared to the DS in which case every system is a big loser sans the PS2).
