Yes, it would be counter-productive to install an Ivy Bridge proc in a Sandy Bridge mobo, and pointless since the prices are similar across the two platforms. They can't discount previous generation boards without the risk of losing sales of the new gen., so for at least another year you won't find any bargains on Z68 mobos. Look at the prices for H67 and P67 boards, still high 2 generations later. Any money you save will be at the cost of performance, connectivity speeds and feature support. Lots of parts will work together, but not all will work well. Also, without out-of-the-box support, you may not be able to boot the board into BIOS to update it for Ivy Bridge. You'd need a Sandy Bridge proc just to do the BIOS update.
