Nope, game was announced in January, and that was it, no news. Everyone I think just forgot about it, I know I did. I honestly thought it was scrapped like RBI Baseball.
I only play sport games, so I checked out the sports related news from E3, and all of a sudden there is PowerPros, and it was complete and done out of nowhere and being demo'd. It was pretty wierd. But it caught peoples attention there I think, because it's a pretty fun realistic game of baseball.
I followed E3 pretty religiously this year and this is the first time I've heard about this game.
If you weren't a big fan of it you had no idea what it was.
