Overall, that depicted concept has a pretty cool look which I really like....If it was an RX type replacement. If that is the new GX, seems like quite the departure from what the GX has been. Can't see that vehicle anywhere close to off-road, not even a gravel road.
That looks too much like the Grand Highlander to be a TX, IMO. It looks like a Grand Highlander render with a different front end slapped on. I think the TX is going to be quite a bit different, especially from the side.
