Here's my quick thoughts on Boom:
The cartoon: really looking forward to this, animation looks solid and I think the 11 minute format is a good idea. AoStH and Underground often dragged at the halfway point (okay, Underground dragged at the first minute), so I think shorter will be better. I'm interested to see how big the Boom universe will end up being with the show + the games.
The comic: Again, looking forward to this. The artwork in what we've seen looks good, and it's a fresh universe outside of Archie Sonic which IMO is too big and cluttered and unreadable (even after the reboot). Bonus points for the comic being canon.
The toys: Eh, I'll get the Eggman one with the Eggmobile and not much else. They look like a step sidewats from the Jazwares attempts. Better paint job, worse movement.
3DS: See my previous comment:
http://segabits.com/forums/index.php?topic=3186.msg68200#msg68200Wii U: Looks alright, but I'm not approaching it as the next Sonic game. It's just too different. Looks more like Jax and Daxter with a sprinkling of Sonic Heroes. Nothing has really grabbed me yet, and the camera during the speed stages is really bad from what I've seen. Hopefully my attitude improves once I go hands-on with it (perhaps at Sonic Boom NYC?)
So basically: Print/TV looks great, games look 50/50, toys look decent but I'll pass on them.
