A leaked slide has hit the web today which details the product lifecycle of existing processors in Intel's lineup. Most notably, there could be as many as 20 processors hitting EOL (End of Life) stage by the end of this year - this means Intel cancels any orders submitted from OEMs and channel vendors beyond that point, as well as stopping all production on said model(s). Warranties will of course remain in place in accordance with the original length.
Specifically, what we'll be waving goodbye to are the majority of LGA775 processors currently still on the market, including the Core 2 Quad Q9650, Q9550/Q9550S, Q9500, Q8400/Q8400S, Q8300, Core 2 Duo E8600, E8500 and Pentium E5400. Further to these, Intel is also aiming to close off production on the LGA1366 based Core i7-970, LGA1156 based Core i7-880, Core i7-875K, Core i7-870S, Core i5-760, Core i5-750S, Core i5-655K and Core i3-530 models.
The PDN (Product Discontinuation Nofication) marked entries in the chart refer to models that precede EOL, a stage in which Intel notifies OEMs and channel vendors that any final orders should be made in awareness of them reaching EOL in the near future.
