I was talking about consumer Market. There is a lot of consumers(well, I think all of them) who are concerned with this, and will not be blinded, by any brand perception.
If anything, that's probably even less likely than AMD capturing 50% of the server market, given how few designs wins they've had with OEM desktops and especially laptops over the last six or so years.
Unless you're talking about sales of individual CPUs to enthusiasts and the like, in which case maybe that would be possible (though probably a very long shot), but as the years 2004-2006 proved, Intel and AMD don't live or die based on what enthusiasts buy.
