It seems that it would be in everyone's best interest if the board was made to support more power right from the beginning
+1 on this sentiment.
I can't speak for others waiting on Klondike boards as I have a bunch ordered through Steamboat, but am tempted to wait for the rev2 boards that allow overclocking rather than accept a rev1 that doesn't.
+2 . I would wait on the rev2 board is this means a delay of 2 weeks or less.
