2012 Lexus GS Spy Shot?

Don’t know if it really classifies as a spy shot, but today on Twitter, Lexus Europe posted a photo of two cars under tarps, and mentioned that vehicle and dynamic development engineers would be driving around the UK — wonder if we could be looking at examples of the next-generation GS:

From the profile of the left car, it has that third-gen GS shape, but the front grille of the right car shows a more prominent nose. Reminds me of the LF-Ch/CT 200h:

Of course, it could just be the two previously seen mules or not even a GS at all — it’s pretty tough to glean much from two cars under cover.
