ZUN and Tasofro have announced Touhou 13.5: Hopeless Masquerade. It's another fighting game. It appears to have a different engine entirely from the other Touhou fighting games. The sprites are also different. While having a higher, resolution than the old sprites, they have less style. I think that I'll miss the old sprites, but that might just be nostalgia.

"It took a great deal of planning until the announcement, I'm sure because it was completed properly and developed with different concept that it felt like years." -ZUN
