Desperate for news and there's nothing yet, but, Unity have done a very technical talk about FM25's switch to a Unity-based UI, if anyone's interested:
Good summary here:
It seems like the switch to Unity was less about the match engine and more about decoupling the code from the UI...
...and that this year's biggest coding jobs have been recoding what FM24 already had (so that it can connect to the UI layer) as opposed to gameplay improvements.
To be honest, I'm still excited for it, because I didn't use any of the culled features (with the exception of "shouts" which were a bit silly).
But my expectations are getting lower all the time!
