Has anyone read anything about what might be replacing the C20X chipsets when Ivy Bridge comes out? I've read about the Q77/75 chipsets that seem to be for 'businesses' but its not clear if those are the replacements or not. I'm also wondering if they are adding anything significant worth waiting for.. mostly I'm interested in saving some power and a 22nm chipset and CPU hopefully should have a lower idle (and slightly lower TDP).
