I can say I regret not picking up Astrotrain for 13 bux plus tax
Mainly because while I knew I'd be interested in Octane (I refuse to call him by his Japanese name, much like Shockwave), I didn't realize I'd really want the upcoming Blitzwing as much as I do.
I haven't had as much hankering for main line product since...well, ever. Those three would look great on the shelf. They fall completely out of my scope of collection, though. Can't just get Blitzwing without Astrotrain, right?
They know how to get me in, those bastards.
