I'm not saying WW is the end all be all, nor do I think it likely that IDW actually would adopt it as part of their own continuity -- and WW's conception of a Prime is inconsistent with Megatron Origin's conception of a Prime, so they can't both hang together -- rather I'm just saying that when it comes to exploring Prime's origins, Furman's "been there, done that," so I wouldn't expect to see him do it again. (And as far as Furman's concerned, his view might be that his WW origin hangs together with the IDW/verse just fine, although with where he's going with the Matrix and the Dead Universe story in Revelation, I seriously doubt it.)
But never say never -- certainly there are some seeds in Spotlight OP that he could explore. And perhaps more to come with Nemesis Prime in the Revelations Saga. I certainly don't disagree that strange women lyin' in ponds distributin' swords (or even glowing bobbles) is no basis for a system of government. Of course, if you believe Megatron Origin, it wasn't the Prime's job to run a government, just a security force -- wonder what happened to the government, not to mention the civilians.
IDW, of course, could have someone else explore Optimus's distant past. Though given the angst that has been expressed over Megatron Origin, and the apprehensiveness some have expressed over a new writer taking over the ongoing in AHM, I shudder to think what the reaction might be if IDW announced that someone other than Furman was going to write the continuity's official OP backstory.
Lastly, given that WW is out there, I wonder how much of an appetite there is for yet another story on the origins of Prime. To be sure, others could be written that could be better, and that could explain his origins in the IDW continuity. But its a big universe of Transformers out there -- hate to see the stories go back to the same well too often. My guess is that it will be some time before we'd see a full-blown OP backstory in this continuity, and it will be because Ryall gets an inspired script from someone aching to do it.
Postscript -- you guys are rough on 'ole Hot Rod/imus. While its a nonsensical name (Rodimus), the animated movie was pretty clever, if not downright inspired, even if (or perhaps because) they had a mandate to eliminate the entire 1984/1985 toy line. And it had a plot that hung together (unlike some other Transformers movie, albeit one that scored a gazzillion dollars more at the box office).
