Jeremy Renner Is Back In His 'Hawkeye' Gear; Most Likely For AVENGERS: AOU Reshoots

Jeremy Renner posted the below image about an hour ago, along with this:

"Tues morn. I find myself in costume again. I just can't tell you why. And it still fits! #marvel #avengers #hawkeye"

Now we know Joss Whedon had scheduled Avengers: Age Of Ultron reshoots for January but by all accounts they were set for later in the month, and, it was widely reported on so why wouldn't Renner be able to tell us about it? Well, maybe he just hadn't realized the cat was already out of the bag on that, but there is another theory. Renner has spoken in the past about wanting to make a cameo on Marvel's Agents Of S.H.I.E.L.D. and that led to speculation that Hawkeye might show up on the ABC show at some point. Now, word is (though nothing official) that they are currently shooting something for their mid-season première on March 3rd -- could that be why Renner is back in his costume? It's a stretch of course, and it's far more likely this is indeed Age Of Ultron related, but what do you guys think?
