Those negotiations seem like they've been going on forever TBF however doubling the life span of the ISS is not to be taken lightly. I know they have another 7 years left but really, do they have to take all of it to negotiate it? There are times when it seems that way.<sigh>

They will almost certainly reach the deadline, even if it will take until 2019.Also, I think Woods forgot something...

The limitation to just the two for EM-1 and EM-2 is already outdated.And one advantage is that it mean almost all of the stack -- except for Orion, the Launch Escape system, and (maybe) the 5-segment SRB's, are all flight-proven off-the shelf hardware. Hopefully that would help with costs, as opposed to building the whole thing entirely from scratch.

... a US built SM means NASA has to pay for it with real budget dollars. At present NASA gets an SM (more or less) for free. Whatever people may think that's a pretty compelling argument for continuing with ESA to build further SM's given NASA's current (and foreseeable) budget situation.

The nose cones will be new on the SRBs. The RS-25 will even be different. Up-rated to over 500,000 lbs thrust with new J-2X controllers. This is why I tend to get irritated when the ill-informed claim that SLS is cobbled together STS parts. Obviously, it is not.Regarding Gerst saying the ESA SM will not save NASA money - that quote has been taken out of context numerous times. He is saying the unit price is not going to be cheaper than the LM SM. What he did not go into depth about is that NASA will not have to pay development costs. They have given ESA their requirements, will be heavily involved in the PDR and obviously work hand in hand with them. Overall, subcontracting this out will ultimately save NASA money whether they continue to have ESA build them after EM-2 or take the design over.

Report that ATV/SM is overweight and behind schedule. Could it also slip the first scheduled SLS launch?http://www.spaceflightnow.com/news/n1401/15mpcvesm/#.UthUePt0lpF - Ed Kyle
Rumors I hear is 6 month slip on PDR is acceptable within current time frame. Anything more than that, there will be an EM-1 delay. This better be one nice Service Module.

ESA will not be confirming it if you would bother to ask them, but the same industry sources telling me that a delay to EM-1 is more-or-less inevitable have also told me that the budget (450 million Euros up till the first flight ESM and spares for the second) has already been broken. Currenct estimates (and we're still nearly four years away from first launch) is that it will go overbudget at least 10 percent.

Industry sources and the ESA chief are two different entities. Industry sources usually have no political agenda to stick to, unlike the ESA chief.
Multi-Purpose Crew Vehicle European Service Module(MPCV-ESM)The PDR was postponed to May in order to give more timeto design trade-offs and to address the excess mass issue inmore detail. A new PDR schedule was agreed with all partiesand all milestones of this plan have been met. The mass wasreduced close to the requirement. The impact of the PDR delayoverall will be minimised by starting Phase-C/D activitiesthat do not depend on the system PDR. A fully consolidatedMPCV-level schedule will be agreed after the system PDR.
To put things in perspective: in January 2012 it was estimated that PDR for the ESA SM would take place in mid-2013. It has now shifted over 10 months to the right, to May 2014.Never mind the fluff about the impact of PDR delay being minimised in the quote above. I have it on good authority that the ESA SM will not be ready to support EM-1 in December 2017.
