NECA Terminator 2 25th Anniversary Tease?

NECA have tweeted the following image of what appears to be a new, or at least tweaked, Terminator 2 T800 figure.

"Happy 25th to T2:Judgement Day. More in works, additional details at sdcc."

Speculation as to what this figure signifies is rife, but the accompanying tweet indicates that this will be a release to celebrate the T2 25th Anniversary and there are more in the works.

Looking at what they have done with Rocky, I suspect we could be getting a tweaked wave of boxed T2 figures using the three T2 figures already done in the Ultimate style (T800, T1000 and Sarah Connor) - or perhaps all three in a set of some kind?
