I think the PSP has been viewed as dead simply compared to the DS. But a resurrection annoucement will have to wait until the new popularity extend beyond Japan. Also this is the biggest release the PSP will see in Japan in it's life.
But in general
I think part of the uptick is the new model. Also I think many Japanease have had the DS for many years and are viewing the PSP as a second console or upgrade. The market has moved more and mroe portable and home console have fallen sharply. I think that with the lack of a DS2 on the horizon many Japanease gamers see the PSP as the only option if they have "been there done that" with the DS.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
