Maybe we're looking at this the wrong way - maybe there will be no "final" window design.As we can see in those images, changing the window design involves "simply" bolting a new forward bulkhead in place (assuming no welding is needed), and probably mating some connectors. If that's true, then the window designs could be thought of as modular.So maybe they will build the SEVs with different window designs depending on their mission (i.e. one design for in space ops, another for surface ops, etc).
There are no /official/ plans, but I've heard some NASA engineers talking about it, and this presentation certainly talks all about it:http://www.sei.aero/eng/papers/uploads/archive/SEV-L2-Lander-Presentation_1Oct2012.pdfAnd JPL's ATHLETE lander proposal used a variant of SEV for a lander.
ULA are getting Masten Space Systems to add Katana rocket engines to the side of a CENTAUR to produce the XEUS demonstration lander. Its intended cargo appears to be a manned SEV.http://masten-space.com/2012/05/21/katana-first-fire
ULA is not involved. They only provided the tank. Also, it is has nothing to do with SEV project. Videos are not evidence.

Does the SEV ( rover version ) use the life support system from the space suits or does it have it's own system for life support based on the life support system used on the space suits that are used for the suit ports?
Came across these two photos of the second prototype - titled as follows:[1] MMSEV: Evaluation of habitability and mobility during tests on air bearing floor[2] Modular Power Systems: Integrated roll-out solar arrays and fuel cell with MMSEV

That has GOT to be one of the most content-empty abstracts I've ever seen, even for something out of a NASA regional center/contractor make-work project.

The people who are planning a this concept need to stop wasting their time with idealized notional plans and bury their heads on the PDR and CDR FMEA documents for the Space Station Freedom/ISS ECLSS, and then compare those to the almost 20 years since then worth of operational data. THAT'S how you're going to do real design work for the next long-duration spacecraft ECLSS.
Someone appears to be designing the MMSEV and DSH ECLSS to work together. The Deep Space Habitat (DSH) would act as a mother ship that resupplies the SEV. I suspect that a Moon base would have to do the same to the rover MMSEV.http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20120008179_2012008351.pdfTitle = Deep Space Habitat ECLSS Design Concept
Deck 2 houses the individual crew quarters and has the least amount of services from the ECLSS. There has been considerable discussion regarding locating stored water in this area to provide radiation shielding for the crew. As the ECLSS intends to launch 450 kg of water, this is a possible location for this water, although the exact means of storage (smaller water bags or larger tanks) have not yet been determined.
