Thanks to
the Distill Web Monitor, my bookmarked
page of Combiner Wars Devastator and it's newest update was caught by said monitor as being online and ready for preorder!
It has since been taken down, but all is not lost! There are several tricks that can help obtain an item on Amazon, and one of those tricks shared around Facebook in the past, which worked to obtain Quickslinger and Brake-Neck, also works for Devastator!
In the link below (which you can go to by clicking on the image below) will take you to the Q&A page for Devastator where there is a preorder button that does function! I just put my preorder in, and it's scheduled for an August 1st release date, and it also seems to confirm that the MSRP is $149.99 USD.

Fantastic news for those of us still waiting to have this beast in hand, unlike
some lucky Australian fans who have him right now!Keep your optics tuned to Seibertron.com for the latest in news and updates, plus the best
galleries around!
