As consumers, we benefit from variety of selection, whatever the product is. In the miniscule market of folding bikes, we're lucky to have much of any selection. Why would anyone look forward to a brand "killer", particularly one as long-established and respected as Brompton? That does not strike me as advancing our cause. Sure a Brompton has shortcomings, as does Dahon and other alternatives, but they must be doing something that others don't do quite as well or they would be extinct by now. Bottom line: rejoice in choice. We get to decide what the "killer" is for each of us individually.
