I explained this about a million times so I will not repeat it anymore. A few weeks back we wrote that iOOTP will be released around the same date as OOTP 15 (+/- a few days depending on how fast Apple reviews the game). The price will be the same as every year ($5) and regarding features, we made the jump to iOS 7 (including the GUI design), added retina support on all devices, added full iPhone 5 support (so you see more info on screens where it makes sense), hand-made a 2014 opening roster set especially for iOOTP, added a powerful player editor (not happy with our ratings? do your own. Want to put yourself into the game: just do it!), improved the AI (e.g. ported the new Player Evaluation AI direct from OOTP 15) and added smaller stuff here and there.
iOOTP is and will always be what we intended with it: a casual baseball simulator for you to enjoy on the road. If that is not what you want, just don't buy it.
