The whole issue with Motorola just slowly losing popularity in general(particularly among gadget enthusiasts) is probably not helping either. They still sell OK, but they have never really got the enthusiast community excited since the OG Droid when the launched the first reasonably high end Android device ever.
I am guessing even the RAZR was expected to have a lot bigger impact than it did, even if it's been pretty successful. Galaxy Nexus hype seemed to do this partially, but I also think the fact it was just not really nice in the hand and had a display not even as sharp as the OG Droid or OD DX really hurt it's appeal with many. Locked bootloader even after promises to try harder to allow such things by the end of last year further killed it's appeal among the enthusiast set that really defines which devices are getting the non marketing generated hype.
