No, it just looks like Apple got first dibs on it. Intel developed the vast majority of Thunderbolt, Apple just helped with the last mile. In time Intel will push it into the general PC market, not just Apple. I wouldn't hold my breath waiting for PC motherboards to be released, however. Devices using Thunderbolt are only just now being announced, and I don't expect to start seeing Thunderbolt on motherboards until late this year, early next year.
I almost have to wonder if Thunderbolt will appear on any LGA2011 motherboards, either as part of the chipset or as an additional chip, although I don't think the former is likely.
