According to Fudzilla, Intel will be EOL'ing (end-of-life) ten models of Core 2 processors.

Up for the proverbial chopping block are:

Quad Core Parts:

• QX6800 R.I.P.
• QX6850 to be replaced by Q9650
• QX9770 to be replaced by i7
• QX9650 to be replaced by i7

These changes make sense, why would one still buy Extreme Edition Kentsfield or even Penryn parts when the i7 Extremes come out?

Dual Core Parts:

• E6850
• E6750
• E6650
• E6450
• E4600
• E2180
• E2160
• E2140
• E1200

Totally makes sense... we are just seeing the transition from 65nm to 45nm; its cheaper to make 45nm parts.
