Call me cynical but I find it strange that someone from a production known for it's paranoid, obsessive secrecy releases this information  at this time and then refuses further  details. Season 6 is one of the worst seasons Teen Wolf has had in terms of night of broadcast viewing figures, this news boosts possible viewing figures for 6.10. It  exponentially  increases the likelihood of viewers tuning in for the premiere of 6b and remaining tuned in to catch a glimpse of Stiles. Like or loathe him 'Stiles' is an immensely popular character and realistically the news he is absent from 6b will make it more likely people won't bother tuning in.

Then there is what O'Brien himself told fans, his filming schedule. Costume Supervisor Daniel Flores allegedly posted a now-deleted photo of himself with Dylan and a caption inferring this would be O’Brien’s last day. Apparently, Flores committed an industry faux pas, by posting a detail of what is going on in filming. Stiles may well be back in 6b in flashback and they have to use the look-a-likes TW hired last year somewhere,  but new footage? I'll wait and see.
