I'm not sure why you're saying to take it with a heap of salt and say "apparently", when that's literally what he said. I went and found the part where he discussed it:

It's around the 10 minute mark.
DC responds to a chatter, saying that they (developers) usually work parallel to each other but that they're now all working together to get out a playable test version of the tech-update, supposedly getting "close".
He's also saying he's working on Jenny a lot because she'll be one of the first stories to experience with the tech-update, and wants people to enjoy all the things they add and improve for her story. At this point its all pretty vague and we don't know what he actually means by this.
But to me it kind of sounds like some content packages (mainly storylines) will be re-released AFTER the tech-update instead of the tech-update being a whole packaged revamp of the game and scheduled updates going further as usual, like we thought. That's just my speculation from what DC said, but I see it happening. Releasing the tech-update in playable chunks instead of waiting another year or more for the whole thing seems to be the best call, even though it's not perfect.
I just hope that they rework all the content they plan on re-implementing, because why the fuck wouldn't you? If at that point they haven't reworked the art and scenes, then what the fuck are we doing?
