I'm very happy to see the manufactures actually listening to the customers. I've always wished that at least one manufacturer would commit to pure AOSP Android, and if that manufacturer is Motorola then they might be gaining a new customer in the near future. That works out really well for me, actually. If the Nexus Three doesn't make it to Verizon, which I doubt it will, then I can pick up the first vanilla Android Motorola phone on Verizon instead.
EDIT-I reread the article and apparently only the Motoblur name is going away. Well that's disappointing. Does Motorola really think just getting rid of the name will make blur any less crappy? Whatever. That's what happens when you get all excited about something before you have all the facts. *facepalm*
