I really doubt they'll do this, as the heat is not an issue at stock clocks for any of the chips, and of course overclocking is not 'normal' and is not covered by warranty etc.
Also I decided to go on Intel live chat and spoke to technical support for cpu's (so as specific a choice as I could make), and the guy I spoke to said they weren't even aware the chips ran hot and there was no plans to release different versions.
So either they just wouldn't reveal if they were going to bring out new versions, or from the first point they really don't care about/see as a problem the high temps.
Also, just as a bit of extra info for those that don't know, apparently the 24/7 max running temp of IVY is 75 degrees, and non 24/7 is 80-85. So at least it is perfectly safe to have some level of high temps.
