Hi Bernd,

I haven't seen that, but knowing Affymetrix I wouldn't be surprised if 
they changed some naming convention midstream. So here is what I get 
from some MoGene 2.0 ST arrays we ran about a year ago:

> oligo:::getCelChipType("../CEL/M1.1 KO.CEL", TRUE)
[1] "MoGene-2_0-st"

And these of course expect a pd.mogene.2.0.st. If Affy changed some 
internal naming convention, then we will likely have to create both the 
pd.mogene.2.0.st and the pd.mogene.2.0.st.v1 packages.

But I'll check with Benilton and see what he thinks.

Thanks for the heads-up!
