Loving the demo. The lighting is so nice it's scary. In my first game I hit a fly ball into the RF corner and when the fielder was running back to the track to make the play, he went in and out of the shadows. For a few seconds the light was so bright on his face that I thought I was seeing the "ghost face" bug from '07 (told you it was scary). Luckily upon reviewing the replay it was just the intense lighting effect at that moment that made him appear ghostly (whew). Pitching and hitting do feel a bit different, but I didn't expect it to be exactly the same. I notice that I am swinging early on allot of pitches, which is not a problem I really had in previous years. I just chalk it up to the breaking pitches being more deceiving and me having to learn to adjust.
I can't really tell for sure if I'm seeing frame rate issues per say, but I did notice a bit of "choppiness" on a few occasions and it made me wonder about this. This was before coming here to OS to read everyone's impressions (I always play for myself before reading impressions). Then I came here and saw that some others were mentioning this too. What I noticed was rather mild and by no means game killing, as it appears some others are seeing it much worse than anything I experienced. Hopefully this will be a non issue once the game is released since the community reps didn't see this at the event last week, and the SCEA guys aren't seeing it.
Overall, I absolutely love the demo. In just 3 (shortened) games I already have seen numerous new fielding animations, cut scenes, and all kinds of new hit variety (I was giggling like a schoolgirl the the whole time). The hitting and pitching both seem a bit more challenging, which I think is a good thing. The commentary is stellar as usual and the game looks better than any sports game I've ever seen. Outstanding job by SCEA as usual. The baseball season just wouldn't be the same without this game, I don't know what I'd do without it (although I'll guarantee that my wife has a long list of suggestions).
