how long will the 3.6 be around?

is there a board that replaces it?

Im deciding if i should develop a project on the 3.6 board if its going to be phased out anytime soon.

also is there version that's physically smaller than the 3.6 that would have the same CAN bus functionality? I've tried a 3.2 but for some reason the code on the 3.6 wont run on the 3.2 for whatever reason, im only using CAN 0

any suggestions would be great. thanks
