There won't be a cdf package created by us. Instead there will be a 
pd.hugene.2.0.st.v1 package, intended for use with the oligo package. 
Note that there hasn't been an unsupported cdf file for any Gene ST 
chips after version 1.0, although Philip de Groot has been making cdf 
packages for the 1.1 chips, and may well make them for the 2.0 and 2.1.


As for a roadmap, these packages will be part of the new BioC release.

We don't make those; Manhong Dai at MBNI does. I suggest you ask him. 
You can get his email off their website:
