Hmmm... No one else bit, so I'll say the little that I can.

Although Apple hasn't announced any plans for releasing Dylan as
a product, we have said that we would like Dylan to be available
for as many computing platforms as possible.  We aren't targeting it
as a niche language, but as a general purpose language.

So, the answer to your question really depends on how successful
we are.  If we're successful, the answer will be "every platform
and every processor".

No other companies have announced plans.

This really depends on what kind of implementation you want.  The
Thomas compiler took four people four weeks, I believe (perhaps a bit
less than that).  An optimizing native-code compiler with a first-rate
development environment would take many person-years of implementation
