Yes, the N810W is tied to XOHM rollout, as far as is generally supposed.

Since Diablo was known to be slated for second quarter (and there had been some bragging about making release deadlines), we expected a release real soon. But it looks like a while before WiMAX is ready, so I don't expect them out soon.

(Before all the shakeup with XOHM, it was conceivable there could have been Diablo troubles delaying the release...)
