You forgot: All these burners are fast, but where is the media? 
16x DVD (lack of media aside) is pretty dang fast. I'm looking forward to faster DL (and, again, cheaper DL media) burns. With DVR-109's and such at the $60 mark, might as well buy now and see where the Blu-Ray/HD-DVD wars go....
Besides, given the way the past has been, you will be able to buy the Blu-Ray/HD-DVD burners this fall, but no media for 'em untill next summer.
