I mean from the games I've played it's getting worse. You can fake the blitz and cover more ground now that stats are increasing. I think the trick there is to not speed burst until after you start running back to cover the cross. I run a lot of play action and have noticed guys using safeties biting on the play fake and still making it back to cover the cross. Especially Kam.
Have not played next gen but I now think it's better than current. There's no way in gods name someone should try and user blitz their opponent and somehow get back to cover a crosser 20 yards down field.
