15-20% improvement is too optimistic. You're looking at improvement that happened from Nehalem to Sandy Bridge. Even a die shrinked Nehalem, Westmere didn't have a 15-20% improvement over Nehalem.
It is normal practice that you wouldn't want your products to compete with each other. That is why you wouldn't see a SB Core i3 21xxK as it is definitely going to have a negative impact on the sales of Core i5 2500K and Core i7 2600K. Now the current race is not so much about raw performance but reasonable amount of performance or similar amount of performance but with less power. The mobile market currently is way larger than the desktop market.
Well I'm expecting a lot on 22nm process.
but we still have to see what is the real benchmark on games.
the current performance increment is based on estimation.
perhaps we have to wait an see on the next generation design.

it looks at it is that there is no strong reason to upgrade from 2500k unless the OC headroom on the new IB is a lot better to justify it. I too was hoping Hexa core for 1155. Seems I am too optimistic
It definitely a no if upgrade from SB to IB.
Anyway it look optimistic on power consumption wise.
