That's my understanding. Which is why I ordered one this evening, after the press release.
If the issue can be kept under control, intel may well not choose to recall motherboards. They can stop current sales and handle the rest through care channels.
Not many people have 1155 motherboards at the moment
Only 5-15% of those may experience some degradation of performance, and possible failure.
Many of those will be able to be guided to switch to spare 6Gb ports
So you're probably left with a very small number of actual replacements needed, spread across 3 years or so. Maybe as a gesture of goodwill they could extend the warranty on all 1155 boards, a bit like MS did with Xbox.
