That being an oversight is unlikely when you consider the timing.. in the end they might change it back (especially considering the bad press) but as I understand it the driver came out specifically for crysis and timeshift? coinciding with the release of their new cards. So most reviews of the new card that used crysis as a benchmark will be slightly inflated -- that was most likely the point of all this, and subsequently what was probably meant to be taken away by the articles about it.
At any rate if all you care about it fps then go nvidia, if you like image quality go ati. Just don't put too much stock into benchmarks using crysis + that driver b/c you're not getting the full picture.
