Put me in this camp as well (another huge ASB fan). While the underlying problem with the commentary is still the same, I think Lyons adds a lot despite that. Of course, I also am one of the few who doesn't think the commentary is horrible (it's just not at the same level as the competition is all). And while I'm a fan of Matt V, it would be refreshing to hear a new voice call the game. Thom Brennaman would be a perfect fit!
Some other general impressions:
-I've also gotten stuttering on 2 different PS3s (an 80gb fatty and a 320gb slim). The pitch stutter is worse on the older system (which is likely a just product of years of heavy use), but I've gotten it on both. Not as bad as some though, thankfully (and it's really inconsistent, so it might be tough to pinpoint, I fear). I do see a fair amount of stutter in-between replays, overlays, etc and also have the menu music skip as well. I felt 12 was much smoother in that regard. Haven't tried without connecting yet though (which might help with the transition and menu stutter some).
-I agree with many who say graphics seem sharper. It also seems something is more accurate proportion-wise on certain players (smaller, leaner guys seem, well, smaller and leaner. It's like height in general is better proportioned). I might just be seeing things (could be better lighting or something instead, I dunno).
- Digging the new overlays and scorebug
-As someone who has terrible vision/reaction, I appreciate the pitch speed reduction. I was able to get around on plenty of pitches using Zone-something I couldn't do so well the last couple of years.
-Fielding animations seem silky-smooth so far and I've already noticed some improvement in hit variety and. It's also less awkward trying to manually field a ball directly of the wall this year IMO.
-A minor thing, but I dig seeing the full roster breakdown in the edit screen.
Good stuff!
