If I remember correctly there were various rankings to tell different players apart for match making. Is 3 levels too small? (It seems that way to me) Are there more levels planned for battle.net 2.0?

Thanks

As stated before there will be a league system in place similar to the traditional ladder system with ranks everyone is used to. You will have to play a couple of games to evaluate your level and then you will be put in a league that fits you best. Each league will also have a lot of subdivisions. After a period of time your skill level will be reevaluated and you will either go to a higher league or a lower one.
