Love the little details and is about time they offered retractable roofs.
I'm happy to finally see Minute Maid Park with the roof closed. I watched a few innings of a game there with the roof closed on an IGN stream and it looks fantastic. I can't wait for the next 4 weeks to pass!
On a side note, in that same stream they used Show Time - the new feature that slows the game to "Matrix" speeds - and it does not look like it will be a arcadey feature. I still doubt that I'll use it but, at least in the stream I watched, using it on no way guaranteed success and they've obviously put alot of thought into how much it can be used (along with the "Perks" in RTTS).
