If you look at the product description on the bandai site posted above, Burning Godzilla is still listed in the line up.
That it does. The lack of a promo shot points to the figure not reaching final stages of development quite yet, so we'll see if it is released soon enough!
And good LORD is the Shinsei Godzilla Tokyo Vinyl ugly. That thing looks hideous from different angles. MechaG, however, just looks that much more adorable.
