I've seen a couple of the new models and they are still yellow. They have new decals....pretty much the same shape as the old only smaller. The outline is silver or grey with a black center. It now says Claas Lexion.

The 740 had a Cat sticker on it...so probably powered by a cat engine. The bigger machine did not have the Cat sticker. Anyone's guess what the engine will be, but I'm leaning towards Mercedes as that is what they have in Europe.

Combines themselves do not look like they have any major body changes. Maybe a new cab, but I couldn't tell from the distance.
