It'll take a while to kill blur. They are going to let Moto mobile run as a separate company with Sanjay still as the CEO. A lot of these companies value their different skins as their marketing, Sanjay is a big fan of the blur. Hopefully they at least strongly improve it.
Though, on that same front, this is probably a key turning point in getting the bootloaders unlocked. The bootloader to the Motorola photon which has very similar internal specs to the Moto Bionic had a leak that allowed it to be unlocked not long ago. So the bionic may have a hope yet through this discovery. The Moto Astrix has already been given a tool to unlock the bootloader as well I believe. The Droid X.... well, that may never happen. Its going to take a while for the carriers (especially Verizon) to allow these phones on their networks again. Weirdly enough, they may just end up requiring you to buy a developer phone and then deny you a warranty. With the bootloader unlocked, Blur and whatever bloatware will be one step away from whatever android flavor/rom you would like.
Brent made a good post on facebook about it. This is a defense move by Google that is making all the hardware makers happy as they get hit by lawsuits from other major companies.
