There'll be the IB-E (Ivy Bridge-Enthusiast) CPUs coming out soonish. The Enthusiast line seems to lag about a year behind the non-enthusiast chips. So we'll probably get HW-E this time next year.
The above link give you an idea what is coming, stumbled upon it yesterday and not really read it much yet but as yamikotai said it's based in ivy bridge tech. From what I did read, it's a bit of a fail when you look at it vs the chip it replaces.
