Shit's been talked about since all the way back during season 1, and they kept saying they'll do it eventually. The tenth season is a historic milestone, so if there was ever a time to make and put out Galactus vs Unicron, it'd be now, for this season's finale. Fully 3D, of course.
Then I guess when that match(hopefully) materializes this season, you can look forward to your thread getting a shout-out, whether direct, or indirect, for all the hard work you've been putting into it, my guy.
The one really good side to Frieza vs Megatron happening, is that since your TF rep is facing a DB character, you know they're going to give it the works and special treatment, most likely. Shit's gonna look badass, I'd wager, and the character interactions should be fun too, provided they don't go lazy on that, which with characters like Frieza and Megatron, they absolutely should not.
