Interview with Hugo by Modders and YouTubers.
Key Points:
Hugo claims the nerfs were his idea and were an effort to make the experience less "exhausting" while preserving the difficulty in the relevant areas. Several nerfs mainly the ones in UAC Atlantica will be reverted.
The lower difficulty of TAG2 was the result of the team aiming to make it a fun romp for your first playthrough, but admitted subsequent playthroughs ended up suffering for it as the lower difficulty reduced depth. Some sections of TAG2 will be looked at for buffs.
Hugo admits the hammer is overpowered and ends up replacing the chainsaw outside of immunity frames. Says the aim of it was to give players something cool as a reward for the end of this journey to power trip on and doesn't want to nerf it. Instead would rather balance (TAG2) master levels around being good with it.
Apparently their bosses take a year to get working. The Dark Lord's healing on hitting the player may get nerfed. Also the execution of the Dark Lord is what they settled on due to the time and funding they were allotted for the DLC due to it being DLC.
There are two Master Levels that are almost done depending on how balance and bug testing goes. Neither of them are TAG2 Master levels and we should not expect those for some time.
