I thought the idea of dropping sockets was rather interesting, personally. The negatives are obvious, and would have been bad, but if they still had high performance offerings it wouldn't be the end of the world.
I don't know that I've ever upgraded my CPU without also grabbing a new mobo and usually RAM. On the flipside, troubleshooting components would be much much easier, you would have one RMA that covered mobo, cpu, and theoretically RAM. If you could buy an i5-3570k on a z77 board with 2xpcie slots and 8GB (and 2 expansion RAM slots) for 250-275$, that would be a great value and cover a huge majority of what users need. If you have problems, you need to troubleshoot the GPU, the PSU, and the mobo, and RMA one of the 3.
I would hate to see the options we have now eliminated, but there are certainly benefits to the other approach.
