I doubt that there will be any significant changes to color and options since it is a new model for '08. Sometimes there are changes due to availability of supply so there is a chance of change. Yes, high MPG cars are doing great, but premium compact SUV class is a new and expensive vehicle category. It is the only SUV category that is not shrinking, but not growing too.

If you can snag a good deal on an '08, then purchase that route and get as much of the $2k in dealer incentive/rebate as you can. The USD is in bad shape and looks to worsen for a while, so you can possibly expect another increase in MSRP soon. I believe Infiniti increased prices in late '07.
