I think many people behind these compilers lack the personal motivation
to integrate the D2 front end.
That may change, but it may take time.

Some reasons I can think of:
- it's quite some work to integrate a new front end (there are a lot of 
new features in D2)
- D1 works quite well for many people and is more stable (important!)
- D2 doesn't offer much gain for many existing projects atm. (features 
vs. stability and transition cost)
- not everybody likes the road the D2 design takes

anyway, gdc has D2 support already (but not up to date/DMD), see http://
