Quoted from konjurer:
There are reasons for showing early and not showing at all. If you don't show it before going to productionj, you'd better be sure that you've your design and quality is rock solid. You're betting the farm on a big splash and the immediate hype cycle to sell you game.. By showing early, you get great feedback to fix things. I see DR is using Agile and Lean practices and these are key concepts in this school of thought (create feedback loops and pivot/adjust quickly). Down side is that you may dilute the hype cycle but for a new manufacturer I think this is a really smart approach.
Yes, BUT the new thing here (if you take their word for it) is that they're not showing us a "near final" product in anything besides the playfield.
They promise to bring the real Innovation (the real cab, more mechs, real art etc.) in march, so that this allready pretty nice game will be kicked up to the next level. - (Again, exeggarated and we'll see what'll happen.)
So if they can keep that promises, there'll be enough "new" again end of march to re-kindle interrest imho.
(At least it's better this way then to do the opposite and bring a prototype wich has more/ better mechs, art, Music in it then the final product.)
For now they announced a prototype, wich would allready be "en par" to the competition, wich (in my opinion) is pretty much what they delivered.
If it's going to be any better, be my guest, much appreciated. 
The only elephant in the room FOR ME is the price of the machine.
Originally talking about Ferraris for Fiat Prices, that has now changed to an essay how to define "value".
