According to a email I recently recieved, AMD have no more BNIB LE Avengers anymore. They had 1 x Only HULK LE demo model left a few weeks ago only.
I am not sure if it has since sold or not.

They have 1 x only X Men LE of each colour left only. 1 x Red 1 x Blue. That was a few weeks ago.

LE Transformers tanked everywhere because people bought the LE Decepticon or LE Autobots only LE models.
The Pro was successful, but the "Half n Half" LE was produced and Stern did admit they produced far too many, combine this with the fact that the
LE Transformers felt, looked and played like a Pro level game only, and this is why so many sat unsold at very high prices.

I think people spending a lot of money on the ACDC versions in Australia, around the time of the X Men release, probably did cause sales of the X Men titles to be a little slower than anticipated.
