No, because scanned during Spring Training '16 means they don't get in until MLBTS 17. They are about 1 year behind due to the dev cycle...they can't frantically go scanning everyone in Feb/March and have enough time to finalize the visual 'assets' and meet a 3/29 release deadline.
So there's hope for '17, but very little for '16 if you want face scans for rookies from last year. My understanding is...
2015 - Player debuts in MLB
2016 ST - Ramone et al hunts player down in AZ or FL and tosses into face scanner
2017 - Face scan appears triumphantly in game
