So, I see a few issues right off the bat:
(1) I realize the appeal of "express, non-stop service", but in a lot of cases this means you're going to dump one or more non-trivial ancillary markets that are basically free money at that point. For example, New York-Montreal should include at least Poughkeepsie and Albany or Stamford and New Haven. Boston-Washington should include Baltimore and Providence. As a note, even the 20th Century Limited had Albany and the Broadway Limited had Philadelphia (okay, North Philadelphia due to routing issues).
(2) A full diner/lounge service is probably unnecessary at the scale of a number of the shorter trips. My guess is that this is a bit of puff and you'd get a cafe with a kitchen to serve some pre-prepped meals (you can do a lot with this) - I agree that some food option is a good idea in the evening (I'd probably want to have dinner in NYC, but if it becomes One Of Those Days [A] and I can't wedge it in for some reason, knowing I can get something from the cafe is some nice piece of mind)
(3) Some of those indicated/implied markets are very different from one another. Chicago-Denver is like 16 hours while New York/Philadelphia/DC-Chicago can run a bit longer by their suggested routes, and that's going to behave far differently from an 8-12 hour service. Here the diner (or something more substantial, at least) becomes necessary because you're now stuck with two meal periods (dinner and breakfast, presumably) rather than just being on the shoulder of one of them (generally dinner).
(4) I want to know who the investors and planners are. This feels a lot like some of the new European sleeper services, but there's enough that's weird that I want to know who is behind the project and what sorts of investment they have lined up. Even a single service with two new sets of equipment would likely cost at least $100m (I'm presuming 8-10 cars per train and going with the Siemens Brightliner cars for my cost estimate), so there's got to be some serious money at play.
[A] Like last night, where my flight was delayed by over an hour at Norfolk due to a busted seat, so I didn't have time for dinner at Atlanta and got into Orlando at 0030...
