I've been in the MWO beta for a while, even before it became Open Beta. I can say that right now the developers are trying to concentrate on fleshing out the balance of combat and features they bring into the game. Hence, many of the maps are small testing out quick game modes in order for them to gain telemetry data. They are also actively working on the new user experience, which is only like 50% complete.
It is going to be some time before the game reaches the type of scale that the developers have envisioned, where there is a larger galaxy to fight over (The Inner Sphere of Battle Tech). It'll be some time before that stuff is implemented, I'd say a year or two. And being an 'free pay-if-you want to' MMO, changes and additions are going to happen slowly.
Its going to be some time before it approaches something like Eve or MWBT: 3025.
