UVS - it's 1/56, I noticed it in a pic from the Nuremberg fair a couple of days ago (see below) - I assume it's in co-op with WG.
(In the wide shot you can see some other interesting stuff - 1/56 Matilda II, a Sevomente & another Italian tank - possibly an M13/14/15 - would make sense as they could use some common parts, An 88mm flak 36 with crew & an Alte 250.)
Fatroc - I imagine making the turrets interchangable wouldn't be too hard.
