Capcom now calling up to the crew with some words on the overall timeline, including shifting the schedule to the right.
Mission Control informed the crew aboard the International Space Station this morning that its spacewalk to replace a faulty cooling system component may be delayed until Saturday.Spacecraft communicator Jim Kelly radioed the word to Expedition 24 spacewalkers Doug Wheelock and Tracy Caldwell Dyson about 9:20 a.m. EDT. Teams of flight controllers, engineers, and spacewalk and robotics experts have made significant progress in preparing for the spacewalk, but may need an additional day to finish working out all the details....The spacewalks are challenging because the crew will be handling ammonia lines at full operating pressure, which makes the lines stiff during reconnection and mating. The timeline for the spacewalk will require numerous “off ramps” to ensure there is enough time for the crew to complete decontamination procedures if they come in contact with ammonia. The plan is to complete the replacement of the pump module during the first spacewalk, and complete the fluid ammonia connections to the replacement pump on the second.
Tracy and I in the 'Quest' Airlock, preparing our equipment for two very challenging spacewalks scheduled for Friday and Monday. The Space Station had a critical failure last Saturday, and we'll attempt to bring it back to life. A 'shout out' and tremendous thanks to our support team on Earth!

Do we know yet which EMUs will be used for the EVA?
