According to sources Intel's LGA 775 socket is very fragile. It is claimed that after 20 insertions and removals Intel won't guarantee an LGA 775 socket to have its integrity anymore.
Only Intel really stand to gain by switching to its proprietary LGA-775 sockets, and the 20% ‘Intel processor bent pins’ returns figure Fudo related earlier is being dumped straight onto the mobo makers. These mainboard manufacturers and their distributors and resellers all work on very tiny margins.
Somewhere around 80% of Intel LGA-775 mainboards we have seen have bent pins, so we struggle to see how a mobo manufacturer can possibly make profits.
