if you want to get technical, the poem doesn't even mention Nexus until relatively late in the poem (after reference to "red and black"). at the beginning, all that is said for sure is that a LTE device, with ICS, will release on VZW on 11/3. then it goes on to say that the nexus brand will ride worldwide for other carriers that use GSM and WiMax.
then, in the conclusion, he says "be it a Droid or Nexus branded new toy..." Well, the only nexus reference was with respect to GSM and WiMax radios. so, one could conclude that the Droid reference was to the one going to "red and black".
personally, i don't think that's right. i think VZW gets a pure Nexus device, as numerous sources have been indicating for months, and then it comes out on other carriers a little later. i just don't see Google introducing ICS, with LTE, on something other than a traditional Nexus device.
