Any new word? spyshot? rumors? release dates? on the "is" replacement?

[B-Line]

So then, if my lease comes up in November, then the only real choice of equivalent or upgrade will be a X5 (E70) 4.8i with a ///M package?
(The ///M package is cosmetic, right?. No actual performance boosts?)

And let me just make sure I understand this correctly:
The X5 4.8"is" replacement will NOT be a X5 4.8"bi-turbo"? Because BMW wants the "is" customer to go X6. So there will be no X5 Bi-Turbo manufactured. There will only be a X6 V8, Bi-Turbo?

So when we talk about the X5 Bi-Turbo, we are really talking about the X6. Or will there be BOTH, X5 Bi-Turbo and X6 Bi-Turbo?
-- Otherwise I really don't understand what is meant my saying that BMW wants the "is" customer to go X6.

Also, does anyone know if BMW will allow me to go month to month on my lease after it matures? Because if the only BMW SUV option is a E70 with 4.8i engine, I will pass and go Cayenne Turbo S or something. I already own a 4.8is and would not want a detuned version of the same engine.

I guess I could also buy out my lease but those deals do not usually make a lot of sense.
