Will the Due be a dud?

Has anyone heard any news since the makers faire, or the possible specs released in September?

I'm stinging to get the 72Mhz OLIMEXINO-STM32 to let my library run free, but my preference would be the due.

Also, are there any specific technical documents for the cpu architecture or would everything be crammed into the datasheet.
What I mean is, are the things like data type sizes related to general gcc 32-bit sizes, or is it specific to the cpu? ( only ever had 32-bit windows n linux, and I think it is a cpu specific thing. )
