Very exciting new video for the things they showcased! I'm going to reserve judgment for things they have
yet to show off like player models and such, because so many different things can happen between then and now. I'll hold onto hope for other things though, like they didn't show any nighttime games so perhaps it's something they're working on.
Most impressive things were the ball physics changes and Heyward's throws after he caught. They've had pretty lackluster outfield animations for a long time, but these actually looked like an outfielder. Very awesome!
I scrolled down your post looking for:
"............ cuz all I hit are DINGERS BABY!!!"
But alas, it seems you genuinely were uncertain, so I'm just glad you got answered.
