Who needs a gs? Well, now that I've seen some serious documentation on the Yamaha Tenere, I'm not so sure anybody needs a gs!
I'm sure that's a great bike!
The first time I saw a Tenere was in Turkey in '94; a French couple had ridden it from home to central Turkey, where I met them while on a rented Jawa. I remember being quite impressed by it and was disappointed that my rental bike wouldn't allow me to keep up with them, and I can't blame them for not wanting to cruise at my pace (we had gone on a day's outing together). The new one looks great.
Have you seen the Ténéré Expedition Tent?
