Kind-of disappointing for me, maybe I was looking too hard. Nonetheless, Zaku II Ver. 2.0 will be awesome, and will definitely be one of future purchase.
From Hobby Shop Midori, a limited production MG Zeta Ver. 2.0 (Green Divers color ver.) will be out in March, which is this month. The price is 5,000 Yen. Get this if you're a hardcore Amuro Ray fan, or if you're interested in its special decal/sticker design, but don't expect anything extra from MG Zeta Ver. 2.0. Anyway, since it's on limited production, that's might just be a reason to get your hands on it, right?
Also, HGUC Acguy coming out in April at a price of 1,400 Yen. Not as sophisticated as the MG Version, but would definitely feature quite a bit of action. What I can guess from the Japanese description is that the stretching of the claw arm will require extra parts.
