Yes it is still the current consensus... due to the timing and the claim of some "reliable" source that I don't recall.
I did post my reasons on that site, just to see what sort of comments it got...
I guess it comes down to how it was listed in the TRU computers... as in, if it had "Generations" in the title. Which in itself, isn't proof, as a number of non-Movie exclusives last year were officially listed as MV4 (Movie 4).1 - If this Devastator toy (rumor) was found AFTER the discovery of the Insecticons and Conehead sets, fans may not have automatically jumped on the Generations Combiner Wars concept as the most likely option (because it was the only plausible option at the time). And Gen1 seems to be the focus of the Hasbro Platinum sets this year.
2 - We have since had store listings of the remaining eight Combiner Deluxes as being Protectobots (for Hotspot) and Autobot Cars (for Optimus), which if true, doesn't leave any spots left for Constructicons. Hasbro have been pretty accurate in recent years on the product numbers they have officially announced at the start of a line.
3 - Hasbro doesn't release several new molds in a boxset (1 or 2 maybe, but not 5 or 6) unless they can't be sold separately (like TF2 Devastator if you count those as separate toys) or are really small (like Micromasters/MiniCons).. especially as a store exclusive, because they can't make back the money spent on creating new molds if it has a limited release. So if Number 2 is correct and this was a new mold combiner in limited numbers at ToysRUs, Hasbro would have to release a really small combiner at that price, just to break even (something about the size of MP Soundwave, which was also a limited edition TRU exclusive... it was slightly cheaper than this, but isn't as complex as Combiners which are technically triplechangers).
And it is worth noting that I don't think it has actually been stated to be a TRU exclusive... that was something I didn't realise until after I posted my points above. If it is a regular release item like Metroplex, maybe there is a chance it is a simplified combiner that replicates IDW Devastator, which would then come in closer to that previous "Titan" price point, and negate my third point.
Hmmm... I wonder if I ask really really nicely, Hasbro Australia will tell us what it actually is.
