Not really, if QT 4.6 was in Nokia's roadmap then having apps from companies (not built using QT 4.6) ready to launch with the N900 would mean those apps would be limited only to the N900 platform. And I think Nokia knows the N900 wouldn't sell enough to justify that (also why companies like Google haven't brought a Google Maps app to Maemo, not enough numbers to justify it). Hence the Meego route so there are more platforms (with QT compatibility) and as a result more users. More users means more developer interest. More developer interest means more programs. So now a company like Google might look at the platform and see that if they build their app using QT 4.6 they can deploy it on Symbian, Maemo (if Nokia doesn't plan on bringing Meego to the N900 themselves), Meego devices.
