No for CDF and yes for CEL. Ben Bolstad is working on the CDF files and 
should have something in December.

I made a cdfenv for what Affy was calling the CenthindAv2.cdf, which 
appears to now be called the Mapping50k_hind.cdf, back when it was still 
a text file. Unfortunately, the IDs appear to have changed in the 
interim because they don't agree with what Affy supplies in their 
annotation file.

I would offer this cdfenv to you, but as I mentioned, it doesn't appear 
to agree with the current identifiers so I am not sure how useful it is.
