I have the same thoughts on this as mark.
I dont think that the new gear will have a detrimental effect on the original gear, as if some one has the new stuff on a hutch or any build it will always niggle them that it is not the original, (my pad set does on my bike) in turn it will prompt people to get the original as and when the cash flow allows. if anything it may push the original stuff up a bit after an initial price drop.
good luck to John i say
Only my opinion, Steve
