I hear you Al,
My Nine is only three and a bit years old. I briefly looked at the 660 Tenere too, the seat height wasn't an issue as such but
with a dickey left ankle and knee, and a crook lower spine the flatter I have my feet on the ground the better

I love the TDM's 'highwayability' somewhere I think the 660 would struggle given our l o n g road distances here. I'm not sure about the fly by wire throttle, look at Toyotas dramas at present
The shaft drive is the main advantage for me, provided it can handle some 'spirited' riding? I would love a test ride on one of these 1200's, maybe by the time they are here in Oz I'll be able to afford to trade the 900? Time will tell!
The fact that it's just been released at the Phillip Island SBK meet is a fair indicator that it will be available in OZ. The Yamaha people say its definitely coming but couldn't confirm a price, they said they were hoping to sell at $18-19,000AUD. All that was over the phone from a mate at PI this morning.
With my 900 now 8 years old and me considering a new bike anyway, it's certainly on my list to look at(the 1200GS is definitely not). Especially as they've given it a reasonable seat height, I just laughed at the dealer when he offered me ride on the 660 tenere, at 895mm riding it would be impossible for me.
In OZ, most people that buy these sort of bikes use them in the dirt etc, not as many show ponies and posers as the UK I guess.
