If I were to explain all the reasons why Sony won't go with Larrabee, my post would span 2 pages. To keep things short, I will just list a few things and clarify them on requiest.
1.) Another unproven architecture will tick off developers.
2.) Intel wouldn't let Sony own the IP, meaning that the chip will always be expensive. Remember Nvidia and the xbox?
3.) Sony adding Larrabee in the PS4 would help intel push it to developers but it won't be 1/10th as effective as is Microsoft did. Unlike Microsoft, Sony doesn't use DirectX or OpenGl, they use their own graphics API, something which would make PS4 - > PC ports hard.
4.) Would break BC with the PS3.
#2 and #1 are really the biggest ones.
Good news Everyone!
I've invented a device which makes you read this in your head, in my voice!
