Those stories got rendered non-canon a while back.

...Clearly he said something about the character so it doesn't even apply to him. And I'm just as interspersed with Ian's word.

Shard is...one of the few characters that truly is ambiguous as to whether he can be used. Ian still had plans for him long after Scourge was taken off cards, at least.

At the moment, it seems like all the characters bar SEGA, SatAM and a select few of Ian's characters are barred. And I doubt any of them will return

From what I've been able to gather, one of the ads wasn't appropriate for the target audience (Advertising a mature rated comic) so it's been recalled. Replacements are being printed though so it's only a delay, really.

With Sonic Live gone, it's gotta be either the Sabrina crossover or Naugus Games (SSS#15 version), assuming that this is genuine and not just a joke on his part.

Scourge still seems like he can't be used based off what Ian has said. Same would likely apply to Moebius. And the No Zone.

Scourge seems like he can't be used, but Naugus is completely safe and will be explored in the future.

The Chaotix had the last full SU arc prior to the crossover, then appeared in the crossover. They've been pretty regular lately.

Ian gave a detailed reason for why SEGA don't want it reprinted. I've quoted it exactly, formatting included, and it's spoilered for size. I'd say it was because SEGA view it as irrelevant. It hasn't been part of the active franchise since the comic ended half a decade ago.

There's already one confirmed major change in age; Charmy is six post-crossover.
