I would love to see Line 6 put out a combo tube amp that just has the power amp and no preamp (backside only) and put it in a more affordable price range to be a support product for existing Pods.  If it didn't hurt the price too badly, it might be nice to have an L6 input that had at least the function of controling the amp class and tube parameters.  The DT25 and DT50 are great solutions if you have deep pockets, but a cheaper companion would be great.  Could you significantly cut the cost by completely removing all preamp funcionality?
