To me, system 11's generally have:
1. great rule sets
yet often have:
2. progressive jackpots (which are stupid for the home market)
So while I'm not clamoring for 2.0's for system 11s -- I think all system 11's should have the progressive jackpots disabled in updated ROMs
I'm much more excited for 2.0's for early solid states that are often missing newer inventions like: multiball, speech, hurry ups, etc.
