Is it possible that SpaceX has decided not to make the landing attempt due to high seas, and instead wait for a later launch for the first try?

TVC problem is non-trivial. May need to de-integrate in order to access the actuator?
Remember that that 6' wave "limit" has been there since CRS-3, so it's certainly not directly related to the ASDS capabilities.

SpaceX is evaluating whether to replace a rocket component responsible for scrubbing Tuesday morning's attempt to launch an International Space Station resupply mission from Cape Canaveral Air Force Station.It was not clear how the launch schedule might be impacted if the company decides to replace a faulty actuator in the system that controls steering of the rocket's upper-stage engine nozzle."A replacement of the component is likely, but no firm decision has been made," [quote/]http://www.floridatoday.com/story/tech/science/space/spacex/2015/01/07/spacex-targets-friday-launch-while-evaluating-rocket-component/21386343/

The ships' captains certainly know something we don't, but whether that's that launch has been delayed due to the actuator, or the landing has been cancelled due to sea state, I couldn't say.
12 hrs??? LZ is around 200 miles out, and the tug makes about 5 knots. More like 36 hrs.
According to @cartman, the Go Quest is actually moving at 8kts -- it can move faster when it's not towing the ASDS, I guess. So if it's 36 hrs at 5 kts, it's 22 hours at 8 kts?
