Every day that passes PSP loses its power. The decline for LBX W is given but the size of decline remains to be seen.
God Eater 2 is PSP's last big title and if BN continues to delay its release it won't end well, at least not for a single PSP release.
Yep. At the start of the year, I said that the end of September would pretty much be the unofficial cut-off date for making a PSP release worthwhile. As expected, sales for PSP titles have been down pretty consistently across the board all year (with respect to comparisons to previous entries in the series), but the sales have held up well enough to still make it a worthwhile platform for games where you can reuse engines and assets from previous titles and sell to the userbase that you've already built up on the platform.
But after September, it just doesn't make sense to go PSP exclusive. The sales decline will be too large to make it worthwhile - better off going with a healthier platform at that point.
The next Gundam G Gen game will just barely squeeze into that Sept window, and it should do okay for itself (and will fit all the criteria that I listed before). But something is going on with God Eater 2. If it stays PSP exclusive, N-B will be leaving a lot of potential sales on the table by releasing the game far too late in the PSP life (much like they let Soul Calibur 3 rot by making it PS2 exclusive at the end of the generation).
By the way, it's still too early to try to divine anything with any confidence - but Xillia 2 is starting to look more and more like FFXIII-2 based on comg. Maybe RE6 is stealing some of the preorder thunder and Xillia 2 will bounce back once RE6 is out - there's still time left - but it's facing a pretty steep drop compared to Xillia right now.
