You got it half right. As mentioned here, there were 2 versions of the MBA-A and these refurbs are from the second batch. Along with newer software, the problems of the rev A seemed to have been managed.
There is no 2nd batch as there is nothing different about the logic boards now compared to last year.
I'm sure software has something to do with better managing of the hardware on the previous gen mba though.
But the thing is that I've owned the mba before and there was nothing really wrong with it, no core shutdown (I think this was just an isolated issue on its own imho) and even with the 80gb model it played hd contents just fine.
