I'd hold of your expectations for now. This looks and sounds good but there is stI'll a lot for Live to prove. We still need to see how gameplay looks during an actual game (oppose to quick clips in a trailer) and more importantly feel the changes.
We also need to see what 2k is bringing to the table. We can't assume 2k will remain stagnant as Live progresses. Don't get me wrong I love everything from Live 16 so far. This is the most excited I've been for Live in ages. But I want to see what 2k has planned before I get overly excited for Live.
