Since there are six regular figures shown, I think this is how Jabba will be divided up.
The pipe rack doesn't appear to have any joints, so that should be one piece. You can clearly see a dividng line for where the tail attaches to the body, and sizewise, the platform should divide into three pieces. That leaves Jabba's head and body as one piece, which I originally thought should be two due to the size, but since only six regular figures are shown in the series and there aren't likely to be chase build parts, this leaves the head/body as one piece.
On the other hand, if there are chase pieces, and previous series have had three chase figures, that means three chase pieces: Jabba's head and body could be two pieces, the gold base part of the pipe itself, and the handset, could be separate pieces from the brown rack. Maybe the gold pipe base, handset, and brown rack could be the three chase build parts. That way, everyone could still build Jabba on his platform. But I sure hope not.
