I mean, you have to look at it realistically. PSP games just don't sell well.

Different companies have different expectations and needs, and XSEED's are low enough that some PSP releases might still be viable.
Every platform is EOL eventually, and a platform that's as generally unpopular (referring to western markets here) and piracy-ridden as the PSP is going to go sooner rather than later once a successor hits.
