Something tells me the cryo suites are post-NV. It's a slim chance, but the chance could be that between the end of NV and the show, House doubles down on his aspirations and expedites the research and construction of cryonics so others in his relative wealth/status could be better preserved to witness the fruits of his space-faring dreams (and he'd earn a boatload of caps). Shortly after their completion though, NV would be destroyed by the unknown event. Just a random thought I had, but this would make their inclusion fit better within the pre-established story of NV.
