Let me first say that I love Ultimaker's printers and their ethos: I am about to buy a UM2 and, to be honest, this news about the dual extruder hasn't influenced my decision really, considering I don' think I would ever really need one.
It was the right decision for Ultimaker, and I am pleased with the extended warranty, and their willingness to give (old) users spare parts when they need them.
One thing bothers me though: the way that this news, of a fundamental change of direction for the company, was announced: especially considering that it is all over Twitter and basically everywhere you look that a dual extruder will be released in Q1 2015.
After researching various 3D printers, I decided on the UM2, and remembered vaguely seeing something somewhere about no more dual extruder upgrade. I spend about 30 mins googling and couldn't find a thing - and then days later happened, by luck, to come accross this thread while on the forums.
This bothers me that it is so hard to find such important information, and makes me think that they should at least put a prominent notice on the main website displaying this.
Otherwise I believe strongly in Ultimaker and think they have handled this whole thing relatively well
