Same here. I haven't ordered the X6 yet, but I have been on the fence for months vs the new Cayenne. I currently own a 997 S cab and this is my 5th Porsche. I owned a Cayenne S when they first came out and I loved it, but like TheX5, feel you don't get your money's worth in options. The new Hybrid Cayenne is just that...new and not proven and I would stay away from it until the at least the first model year. Look at how many X6 hybrids are sitting on dealers lots!
TheX5 and I have had many conversations on another forum about the getting the Cayenne and an X5/X6. I am still on the fence. Porsche's are solidly built and if you plan on keeping it, you could really get up well over 100,000 miles with regular maintenance and not have too many worries. Given my BMW experiences, I can not say the same.
But, I love the looks of the X6. it's very unique and I love the stance. The Cayenne is softened from the old model and there are so many look alikes out there, even a car lover like me has to do a double take on what it is!
If you do deal on one, the going rate on the lot is about 6-7% off MSRP. But, that can change since Porsche's allotment to dealer is cut way back, so the dealings could get less off MSRP.
Hope this helps as well! Good luck!
