Newbe but Need Hardware Floating-Point
If you need something *now*, the options are a lot smaller. I would seriously consider a floating-point DSP or a full-fledged ARM Cortex A8. However, do you *really* need floating...

AVR32 AP Serie
The full MPU market is a tough one to crack, especially with ARM around (and Atmel making ARM parts at that). If I had to guess, Atmel would probably focus more on the smaller...
