How much work is needed to support atmel in your opinion?

AVR is 8-bit harward architecture while D is designed for at least 32 bits. Besides that AVR's have from (less then 1) to (a few) kB of RAM so it needs another standard library with no GC. Guess that's a lot of work, so don't expect it any time soon even if someone will try to implement it.

I think you'll find that most arduino projects are using a much more
capable avr chip, probably avr32 chips.
I wouldn't expect D will ever work well on 16bit microcontrollers, but on
32bit avr's I can't see any reason from my (limited) experience why the
toolchain wouldn't just build and work out of the box (at least under
linux).
You'll basically need to write the runtime yourself. If you avoid the GC
and OS stuff, you can basically stub out phobos, and you might be able to
run raw code quite easily...

There are 32 bit avrs. Search for 'AVR32'. "Alex_Dovhal" <alex_dovhal@yahoo.com> wrote in message news:jgggnk$2vev$1@digitalmars.com...

Atmel also Arm based 32bit microcontrollers On Fri, Feb 3, 2012 at 9:44 PM, Daniel Murphy <yebblies@nospamgmail.com>wrote: > ** > There are 32 bit avrs.

Never actually used arduino, but it's site and wikipedia mentiones 8-bit devices http://en.wikipedia.org/wiki/Arduino . Here also http://arduino.cc/en/Main/Hardware - all PCB contain 8-bit devices.
