Great article and renderings.

Good visualing of the NRHO:

Looks bizarre in the Earth centered inertial frame.

Has there been any info on what would be use for the lunar landing portion?

Altair back from the dead?
Don't worry, things can only go up from here.  Even if it explodes, the force of the explosion will probably make it go up a little.

NASA's notional mission sequence sees the DSG in NRHO primarily as a staging area for the Deep Space Transport to make a 300-400-day "shakedown" cruise followed by a transit of the Mars system. Crewed spacecraft to the lunar surface are not in the picture. Likely partners on the DSG, like ESA, may have more lunar surfaced-focused ideas.

There are currently no plans for landing on the lunar surface. The current raison d'etre for the DSG is to field-test tech for going to Mars and being the assembly location for a future Mars transit spacecraft.

I suspect any lander is going to be halfway between the Apollo LM and the size of Altair. And if NASA can't get the funding; perhaps an ESA/JAXA consortium could be asked to build it. But then; they have to get funding appropriations approved, too! The other option is to ask Commercial Space - including the big guys Boeing/LockMart/Northrop-Grumman - to compete for the contract. I'd love to see Elon's proposal, assuming he was even interested.

ESA, in particular, seems more interested in lunar surface activity. At some point, there will be a "fork in the road" for DSG partners if NASA still champions Mars first and the Europeans head for the lunar surface.

Why would NASA want to co-manifest Orion on the PPE deployment mission?  The PPE module could be much heavier if Orion wasn't tagging along.

NASA owes the National Space Council a report on returning to the Moon. I suspect that report will include the DSG and high level details on a landing option

You got that backwards. On Orion missions after EM-1, there will be leftover payload capacity. It's almost a free flight for the DSG modules. It also gives Orion after EM-2 somewhere to go.

I'm pretty sure Elon already mentioned his proposal- High elliptical rendezvous refueling.

Yup.  With the current architecture, this is the best utilization of current and in-work assets.  Also allows private sector and other country agencies to participate in a straight forward capacity.
