The new Stegadon (for Lizardmen) will be a plastic kit. If you look at the base, it appears to be a chariot base (two inches by four inches), and if I'm looking at it right there's some significant overlap on both front and back. That's one huge figure. The skinks don't even look crowded.
The rumors also indicate that the Stegadon is more than a Rare slot, and so multiples can be taken per army. I couldn't be more excited.
