In this instance most likely you are right, because of the small clock speed bump. But how about i7 920 D0 vs i7 960? Are those are the same quality chips and u can easily add +0.55 GHz to 920 with no voltage adjustments? I tend to think the answer is no. As i see it, with this move intel just says to itself that yields are getting even more mature, so it is time to boost clock speed a little and discontinue previous sku (and because there is no binning, 2600k is unmanufacturable at this point; only 2700k comes off the lines). Right now the diff between chips intel shipped now and half year ago is almost unnoticeable. But as time goes, quallity delta will become bigger and it will be more noticable. And of course, upgrade from 2600k to 2700k undoubtedly would be great fail : ).
