And were is he going to find a motherboard? You are right though the i5 2500k would be worth the wait. I overclocked one on recent build @ 4.8 stable. It is a beast of a cpu. Hopefully they stabilize the issues on the sata ports. If he is going to build a new system now, I think that he should use the 1366 board because they are proven.
Yes, but it's not much of a wait now as the first fixed boards are being released later this week and full retail in April.
