New polybags for 2015: Some info

If some of these bags are already known (I have completed the list with the official LEGO references already known) and have already been the subject of a promotion at LEGO or elsewhere, the three polybags in bold in the list above are interesting:

The one identified as containing a version Episode vii of C-3PO should logically allow us to get the droid in its new version with a red left arm, like seen on other derivative products.

The polybag identified as "SH Avengers Hulk"could finally allow us to obtain a new version of the character in minifig format with his outfit seen in Avengers: Age of Ultron unless it is, but I think it is unlikely, of the reference 5000022 output in 2012.

The bag identified as "SW Stormtrooper"can optionally be unpublished and become a Army builder interesting or contain the Stormtrooper Sergeant if it is in fact the polybag 5002938 already released.
