the engine layout is very similar to the TDM's but there are some differences. E.g. the room at the right side for the cam chain is larger than in the TDM 900 one. The size of it might even indicate the use of sprockets i.s.o. a chain. The rear frame mounts look a bit different as well and I don't recognize the hole in the front center of it either.

But then again, no surprise there. To get a higher bore version from the 900 twin of the TDM some design changes are inevitable.

That is nothing like the TDM engine, looks more like an early prototype (obvious). DOHC by the looks. Be interesting to see what they come up with a trailly looking road bike or a bike with genuine off road potential.
