[Archie Comics headquarters, 2013. Ken Penders can be seen marching off into the distance with his characters.]
Archie: Whew! That was a fun lawsuit!
[Sonic runs up to Archie and hands him a stack of newly-printed work-for-hire contracts.]
Sonic: Here you go!
[Sonic runs off.]
Archie: Huh? What am I supposed to do with these?
Jughead: I know!
[Jughead eats the contracts. Archie and Jughead start doing the Can-Can.]
... That must be how it happened. If you don't believe me, listen to what Ian Flynn says here. Sounds like the post-reboot stuff is in the same boat as the pre-reboot stuff!
In other words, all material ever created for the Archie Sonic comic is legally off-limits to Sega. Raise your hand if you're still wondering why they revoked the license. xD
What this means, in practical terms, is that you won't be seeing the likes of Thunderbolt, Nicole [as a Holo-Lynx], or Eclipse showing up in the IDW series.
Archie Sonic Online definitely softens the blow, and as far as I know, the DiC stuff is on solid grounds. Still, it leaves me wondering what exactly is going on at Archie HQ, lol...
