It is a good question. I think there is still a place for 8-bit processors. I think this launch narrows that space somewhat, and narrows the space for 16-bit processors even more
I agree with Alistair. Even the low cost, high performance the 8-bit Mcu's will be in the market for a long time. 8-bit Mcu's are easy to use and program. there are not ( at least i do not know ) 18-Pins or 40 Pins DIP type package 32-bit Mcu's. All are Smd type packages. Most people who use 8-bit Mcu's are not capable of soldering smd parts. Also flashing 8-bit Mcu's are easier and cheapier than 32-bit ones.
16-bit market ? I know Pic24 and Msp430 MCUs that are widely used. Especially Msp430 is perfect with its low power features. Off course there are other companies produce 16-bit MCUs like Freescale, Zilog, Infineon but those are much more application specific not so much for hobiests, i think.
Yes, that would be good to learn a manufacturer's perspective, if any would comment.
8-bit is here to stay for a very long time. It is simply unbeatable in what it offers. The issue is really one of why are 8-bit users not using 32-bit when they should!
