Yeah. That aint gonna happen. Haswell-E is the HEDT platform. Haswell-E is going to be priced similarly to the current HEDT platform. That's a guarantee. Pretty sure the pricing was already leaked, but it's going to be the same: quad core locked at 300$ (HEDT), 8 core unlocked for 550-600$, or the super silly high clocked version for 1000$. If you're using scientific software or productivity software, the HEDT Platform makes complete sense and the price premium is justified. For pure PC gaming, the price premium isn't justified for someone on a budget. It's like 500$ or more over the mainstream platform, which even with a quad core i5 and mobo you can probably buy a combo for around 300$. As opposed to 800-900$ for an x99 mobo with a 5960X. Now for games that perform the same on both CPUs. 500$ more? Yeah that doesn't make sense. But it does depend on what the user does OUTSIDE of gaming.
If you need the power, go for it, but for gaming and nothing but gaming? No. Just no. Suggesting an HEDT platform for gaming, for someone on a budget (i'm not sure if this applies to the OP or not) is pretty silly since the mainstream platform will deliver 100% of that same performance for 99%+ of all games. You would literally pay 500$ more for 0% more performance in the vast majority of games.
Now, 8 core CPUs are exciting; but the software and games that take advantage of it just isn't there yet. For real work? Yeah, HEDT makes sense there. Absolutely I would get HEDT if I used it for that type of stuff - video editing, photo editing, so on and so forth. If the software/games situation ever changes, i'd love to get an 8 core CPU for such a purpose. But that change will take time, and developers are catering the majority of the audience which, (especially with mobile in consideration) are generally on dual core or quad cores at best. The steam hardware survey bears this result: VERY VERY few PC gamers are using hexa/8 core CPUs. Nearly everyone is quad/dual. The steam hardware survey is 100% inclusive of course, but i'd say most gamers use steam on a regular basis; there's simply not much incentive for devs to make use of hexa/8 core CPUs yet.
Don't get me wrong. I do hope the software situation changes. I would _love_ for more games to take advantage of more than 4 cores. But it just isn't there yet. When it does change, i'll be the first in line to get an HEDT platform.
