Thom's predictions for 2013...

And, as long as the D400 was ready, they would sell more of them if they announced it before the D7100, just like with the D800/D600 which would generate more profits.  So, the only reason I could see the D400 not coming first if it wasn't ready (problems with low noise at 8fps at 24MP perhaps) or if they felt some competitive problem that compelled them a different direction.  From the pure maximizing profit point of view, I'd sure think the D400 should go first.
