Before I move onto the particulars of this, I just have to say that I'm so glad games are still being made for the PSP.
(Normally I'd follow that up by saying I wish people were still making games for the DS--aka my all-time favorite handheld--too, but I'm enjoying my 3DS so much it's hard for me to pine too much for its predecessor these days.)
As for which in-the-works (and just-announced) PSP game we're talking about in this instance: it's called Bakumatsu Rocker, and it's being developed by the folks at Marvelous AQL.
Oh, and as is shared in the header above, Bakumatsu Rocker is a rhythm game set in feudal Japan.
For those who are interested, here's a slightly beefier description of this 2014 release (on Feb. 27) courtesy of siliconera.com:
"Set in the final days of the Tokugawa Shogunate, the Shogunate is using the 'Heaven’s Song' to brainwash people and rule the country. Freedom fighters are 'rockers' led by Sakamoto Ryoma."
Sounds (and looks--based on the screenshots above) great to me. Now someone just needs to start accepting pre-orders for this sucker.
