"Motorola has been sluggish in delivering promised updates for its existing phones, so we'll have to wait and see if things improve going forward for the new Razr."
If it were merely a case of being "sluggish," that would be one thing (and bad enough), but Motorola has also "changed their mind" (euphemism for lied) and decided not to deliver promised updates/upgrades for some of their phones. Here is the disclaimer Motorola uses on their Android software update schedule webpage:

I don't use their products, but I would trust Samsung to deliver on their promised updates/upgrades. Motorola, maybe you'll luck out and get them, maybe not. It's a crap shoot!
