has what they purport is the Intel CPU release cycle for the next 3 quarters ( Q3 08, Q4 08, Q1 09 ) and it shows:

1)a decent price drop for current generation CPUs in Q3 08, plus 2 new variants of the current generation

2)release of Nehalem in Extreme and Performance categories in Q4 08 at 3.2Ghz

3)release of Nehalem in the Mainstream category in Q1 200 at 2.93Ghz.

Stock at 3.2, nice! That seems like pretty good news for the next 6-9 months in the CPU arena from Intel, it will be interesting to see AMDs' counter.
