Yeah, I think so too.
Not sure but after I saw the leg last ep I was thinking he can probably control the timing of his healing now after 4 more years of practice, along the lines of how Annie showed us it was possible to focus hers (like she did by prioritizing healing one of her eyes) in her Titan form or like Reiner with his arm at the castle during that night attack.
I guess he could have been keeping up appearances after the arm bandage got put on but if not then he was seemingly able to hold off healing his arm until he was ready (we saw his arm emit smoke right after he took off the bandage and was preparing to transform when they revealed they were the Armored and Colossal), and now knowing that he was the Armored he was clearly able to hold back his transformation despite the pain of his arm getting bit into by that Titan, so I think it's possible maybe Eren can control his healing and better hold off his transformation since he's had 4 years to improve since we last saw him.
Loved this ep. Re-watched it and even on second viewing it still feels like lots of things in motion (Since I'm not watching ahead I feel like this is one of those deceptive ones that there's still more I haven't noticed yet that I might on future watches after we're further in lol) despite the calm before the storm and then there was all that feeling of shit's about to go down and kick things off with that tone toward the end and that post-credit cliffhanger.
