You know, though, this is like the oldTrek/nuTrek arguments a few years ago - saying that "the new version isn't all that" carries the implication, intended or not, that the producers tampered with and damaged something that was working.
I don't think that's true in either case. Just because they may have alienated some people by particular changes to things that they liked about the old version, or haven't immediately fulfilled every imagining that fans had about what the new stuff might aspire to, doesn't even strongly suggest that the new approach isn't going to be an improvement across the board for the company.
Right now, they've got one month's more extraordinary success than they could point to last month. When "sales dip" will they fall further, faster, than where they were, oh, three months ago? And does it make any difference either way, given that they were on a predictable path to extinction anyway?
I'm sure that, just like Trek, there's no shortage of people out there on the Intarnets who know exactly what they would have done instead that not only would have been universally recognized and hailed as better than this but could not have helped being stunningly successful in every respect.
