I suspect the same, though it will probably be too little too late for me, since I was already losing interest in BG3 a year ago. There are simple things they could have done to make sure that the EA remained fresh and enticing while it was still underway. More faces and voices, more body types and outfits and colors, more recruitable companions and a larger party etc, but the impression one gets is that they think 'Well, if we give that to them during EA, then there won't be anything left to wow them on release..." which to me seems kinda backwards.
When the new content is pretty light and the level cap is low, things like a robust character creator and more variety in party comps or PC looks would have helped it from getting all stale. As it stands, when that a stuff drops in 2023 or whenever, I'll just think 'they should have done it a year ago' when it might have made more of a difference in EA player retention.
