Okay, time for a little speculation. If we for a moment consider that the regular, individual release Constructicons do not combine, then what are the odds that someone will work out a set of instructions and add-on parts to make them combine into Devastator? Very, EXTREMELY likely, I'd imagine. Look at the Fans Project City Commander or any of the other accessory packs that fans have developed lately. Heck, check out the Unicron.com accessory pack for Transformers Animated for an excellent example involving giving Animated Ratchet his proper magnets. Now, what are the odds that Hasbro has already seen this trend and anticipated it (if the Constructicons do not combine on their own) by designing a proposed Devastator accessory pack? A pack of add-ons that allow you to combine the Deluxe / Voyager Constructicons into the giant. Maybe even having the parts form a separate construction vehicle like this mysterious backhoe when not in use. I would imagine this is very much a possibility. Accept the fact that if Hasbro doesn't release an accessory pack, then someone else will, and it is all but a foregone conclusion that we'll get something to combine Devastator. And if I know Hasbro they will not miss out on a huge chance like that. I would imagine, therefore, that we're going to see just such an accessory pack offered at some point. Possibly through HTS as an online exclusive, or even through the TFCC, or both.
