nikon D7100 - how will Canon respond?

The D7100 looks excellent in every way and generally a great replacement for the D7000, but that 6 shot RAW buffer is a non-starter for anyone into action shooting. Why bother with 6-7fps and pro-grade AF?

At the current price level of the 60D and 7D, Canon don't necessarily have to respond that soon; only their sensor is outdated, they otherwise match up pretty well with the D7100
