Since I assume DT line i5's will assume the role of lower binned i7's with HT disabled, they will be true 6 core, assuming that a HT core acts as 1/2 a core on average, then QC plus HT is ~= to 6 core. Depending on where that is IRL perf, it would be between i5 and i7 and likely marketed as such.
And we thought intel had too many skus already
