Regardless of what may happen with DC I would always say book redemptions as soon as you are sure of your dates as you never know what might happen. However I wouldn't go rushing to book redemptiosn where I'm not quite sure just in case something dramatic changes in the next month or 2 with DC. I personally don't expect as much doom and gloom from the LH takeover as many here. I hope and expect I will be redeemping DC miles at the same rates for the next year at least (so that probably means C+M will be scrapped effective 1 FEB!!)
