I've done some quick mini-research regarding the upcoming anime titles and their broadcast details. Outside of the obvious one (Carole & Tuesday for Netflix), the rest of the anime all seem to be available normally so I wouldn't worry about titles like Fairy Gone or We Never Learn.
The real interesting curiousity that I have for this Spring are two things; which shows will be exclusive to Funimation, and whether or not we are able to legally stream One Punch Man Season 2. If anyone wants to make some predictions feel free, I'll probably provide my own below.
