Certainly they remain strong in the embedded market (I do like the edgerouter X a lot), but as for their current direction or future product lines, not a clue. I used to know someone over there, maybe he's restored new directions. Last I recall he was busy obsoleting a whole lot of instruction space in order to make room for "new stuff". He'd even asked me if adding an invsqrt to the instruction set would help, and I sadly replied that that bit of codel was totally invisible on a trace..... I really like(d) mips. ton of registers, better instruction set than arm (IMHO), no foolish processor extensions.
