It sounds like that 2 year CRS contract extension will come just at the right time.
Now Thales can keep the PCM assembly line busy for another year or two, so they don't need to shutdown before the follow-on contract comes up. Since there won't be an ATV, I assume the larger capacity Cygnus would be preferred over the Dragon for most of these flights.

That's an interesting assumption (but not a surprising one from you, Steve)...

From the article, a quote from the Thales Alenia vp:
“There has been talk of a follow-on order for two to four modules, but with NASA having decided to extend the station’s life to 2024, there are eight years of operations beyond our last delivery, and it is eight years that, unlike the past years, will not have ATV deliveries,” Quaglino said. “So we would expect an order at least as large as the original CRS.”
So this represents the follow-on order, most likely, not the large order they wanted. I don't think it's as simple as a production line shutdown, but the ability to plan out orders from suppliers and such.
I doubt either Dragon or Cygnus would be heavily preferred, but both may need increasing capacity and/or increasing pace of launch.

Well, there is no need to replace any down-mass from the ATV, but there is a huge hole in the up-mass budget.
When NASA is planning logistics, isn't it easier to plan fewer missions with a larger cargo ship ? Fewer missions means less total overhead, right ?
Besides, the anyone but SpaceX in me says they want a vendor who launches on-time. With an increased number of cargo missions, they can't afford multi-week slips in the schedule.

Goodbye Antares 120. Next step is 130 with the Castor 30XL, then upgraded Cygnus.

I am wondering if NASA could do Bi-contract CRS with Orbital and SpaceX. Where Orbital could do a MPLM with Service Module that Shuttles sent up and SpaceX could provide the rocket.

It wouldn't be too strange, given the fact that SpaceX has already carried stuff built by Orbital for third-party customers. That said, though, I think SpaceX wants to exercise its Dragon as much as it can.

No. The companies would have to do it on their own. They would have to propose it together. NASA's conops for cargo delivery to the ISS is to buy a service (items delivered to the ISS hatch). It is up to the contractors to determine the solution.

Is there a diagram or data comparing the current Cygnus to the upgrade? I've just heard it's "bigger" but nothing saying how much bigger. 50%?

This diagram shows the difference in size for the two versions.

Here's another slide giving mass capabilities and some dimensions (from a presentation on using Cygnus as a module to augment Orion on BLEO missions). The first two versions are as used for CRS to ISS.

I was close. 38% bigger by volume.

During the CRS-2 press conference, it was mentionned that Orbital/ATK has the option of bringing up a spacecraft with unpressurized cargo only.
What might that look like? Like half a Cygnus with one end missing?

http://space.skyrocket.de/doc_sdat/cygnus-ucm.htmBasically the Cygnus service module with an ExPRESS Logistics Carrier on it.
