Definitely not soon unless you mean a few weeks to a month, he has to make the small-medium story quests, boss fights (weeks ), and the awakening system since awakening will probably have a story quest attached to it.
There could also be unique quests he has to code like the stealth section in Fort Talos (I doubt it but it’s possible)
what is being delayed
early access will stay on its set date and release is the only thing that will be affected
then again, early access is free so it wont matter
