I agree completely. I was simply restating the longview goal of the work we are doing (above and beyond adding armadaXP/370). I probably should have given a time reference for "This will lead to..." :) Also, I have a feeling that not all legacy boards will get converted over. If there is no interest or no way to test, certains boards may get deprecated. thx, Jason.
