Its been mentioned as a possibility for UFC 88, which very well may make that card the most stacked UFC card of all time.
This article also has it as a possibility for the free card in London.
Its a shame that Yushin broke his hand, because while thats a mismatch (most fights with Anderson nowadays are) it has some history behind it, and it isn't near the mismatch that this one would be.
And this article has Dana stating pretty definitively that it'll be at 88 making the main card look as such. It also mentions that Anderson may fight again at 205 on the New Year's Eve card.
