I think you guys are not getting the ivy platform. Intel has two phases during development of a platform called tick tock.
One is moving and innovating to a new platform(tock), in this case the sandy, the next is a derivative and improving the manufacturing, power consumption and performance ratio on that platform(tick), this case the ivy in 22nm. They call ivy tick+ because of the gpu enhancements which is in preparation for another tick phase, Haswell.
This is the way Intel develops its cpu.
Not really bad new for me because I don't have sandy and on a standard non oc'd setup the performance of 10-20% is a big deal especially if you will be paying the same price anyway for sandy and ivy, in that case its a no brainer to get ivy.
