And it's rather...anticlimatic?
After that last declaration from Chiaki ("Perform a concerto with me!"), there's nothing of that sort in this chapter, just the characters proceeding in their musical lives...(and hell, Tanya and Kuroki are both STILL in denial...)
I know there are bangaihen chapters to follows, mostly dealing with what becomes of the side characters. Will they do one final chapter on Nodame and Chiaki?
