Rumble does look like he could be Soundwave's little friend (hopefully in the cartoon as well), just like Laserbeak is.
He will be mine, but does he actually include a DVD?
Kup is great and won't clog the shelves unlike the United/Generations figurine for a few reasons:
1) You can repaint him into Ironhide if you want;
2) He has better articulation; and
3) In case he isn't redecoed into Ironhide, then we could give Kup's cannons to the Arms Micron release.
And while Kup looks nice next to Hot Shot, Iron hide looks nice next to Optimus.
And Dreadwing? Well, he could sell more than his brother, Skyquake.
