I'm not too optimistic we could actually get the final release out during February, assuming we want to allow a couple of weeks for people to test an RC.
Does the Haskell Platform actually want to commit to using a GHC release with "tons of [new] stuff", that has had little testing, days or weeks after its release? I thought the idea was that it would favour known-good releases over the latest-and-greatest, but perhaps I misunderstood or the philosophy has changed.
