Interesting, so that's where MIPS is surfacing :)

A little light on the peripherals (no 32 bit timers?),
and only 10b ADCs (?!) but a good code-size range,
and ahead of the now venerable ARM7's

Will this cannibalise the dsPICxx market ?

A $50 starter kit is impressive
(if a bit vanilla, and no mention of code Size limitations ?)

The first devices appear to be pin and peripheral compatible with 
PIC24/dsPIC.

"The MPLAB C32 Student Edition has full optimizations that never expire and 
a compiler code size limit of 64 Kbytes. To activate the Student Edition, 
insert the free license key during installation. Without the license key, 
the default code size limit is 16 Kbytes"

You can download the source though:

But how much will they cost?

Also, why don't they have a 40-pin DIP version :-)

PIC32 family come in 64- or 100-pin TQFP packages.
$2.95/10K PIC32MX300F032H 32KF 8KB RAM 64-pin TQFP
$5.30/10K PIC32MX360F512L 512KB 32KB RAM 100-pin TQFP

Any idea how they compare operationally ?

So whose compiler is this based on ?

If it is open-source, why all the 16K/64K-with-key timed-optimize fancy 
footwork/nonsense ?

Its based on the MIPS GCC implementation, but with Microchip bells and 
whistles.

Don't know, but as per my previous link, you can download the source.  You 
can also download an unlimited binary from the MIPS site, but don't get the 
bells and whistles - eg automatic population of the correct interrupt 
vectors, etc.

It just needs external DRAM support, like the MX31 ARM stuff from Freescale.

It's a 32-bit CPU, so I should be able to run Linux!  Maybe in the future.

What would be really nice is a multi-chip module so that it still looks like
a microcontroller, but it has 128 MB of RAM (one 1 Gb die's worth).

I heard from a compiler vendor that they were expecting Microchip
to take their architecture to the limit by releasing a 29 bit processor,
I guess this was canned at the last moment ;-)

Should give the MIPS architecture a new life.

Would be really great, considering that you do not have an external bus 
interface ;-)
You could perhaps connect another processor WITH a bus interface to the MCM.
Plenty of those around.
