What they consider a small number and what we consider a small number are two different things.Apple has officially stated that it affects only a small number of machines
I think the anecdotal evidence of them extending a repair program and making a public acknowledgement is telling insofar as that its not so small that they can ignore the problem.
To take another way, has apple acknowledged the issues with the 2011 MBPs yet? Those numbers are not small it seems and yet they're not doing anything for them, so by inference their attention to the 2010 issue seems larger then the 2011 GPU issue.
