According to Figsoku.net, in an interview at Tamashii (here), one of the SS designers (whose name is inconsistent in machine translations) states this:

Quote:

オーズにとってアンクは欠かせませんよね。
実は真骨彫製法で腕だけの状態と人間態を準備中です。
アンクを演じた三浦涼介さんの独特な存在感も、骨格から作ることで立体も似てくるんですよ。

(Quick and dirty Google translate)
-Ankh is essential for OOO. In fact Shinkocchou I am preparing the state and humanity of only the arm by the manufacturing method. The unique presence of Ryosuke Miura, who played Anku, is also similar in 3D by making it from the skeleton.

It's being taken as a fact by Figsoku that Ankh is coming, but without more proof it could just be blue sky stuff.
