Aside from the issue of BG3 as an esport (never going to happen), it is quite probably that a DM mode will be added in the future, so that would sufficiently allow a 5th player to be the one streaming and providing a lot of the “commentary.”
That is great news, Warlocke! It would be very satisfactory, but I fear the DM would be highly busy, so a 6th "player" would be needed.
There is some precedent for sport in D&D already, as you will recall: Hill Giants. They love hurling boulders and competing against each other in this way. Perhaps you or some of the others here can remember some more activities that would form part of a monstrous Olympics.
It’s not really news, per say. I don’t think that Larian has confirmed it, but I’m pretty sure that it has been directly mentioned that Larian knows some people want this and it’s on their minds.
BG3 is a turn based game, so nobody is under the pressure of time to provide commentary. Any co-op streams will likely involve lots of banter, and that is what the likely audience will be tuning in for, not a play by play breakdown.
And again, BG3 as an esport is so unlikely to happen it is functionally an impossibility. It doesn’t have any of the immediate, visceral excitement of major esports, and it isn’t designed to facilitate that kind of following.
Could a small, dedicated community of competitive players emerge? Sure, but that isn’t an esport.
I don’t see any way that the existence of competition within the lore of FR at all lends BG3 to esports. That’s like saying because there is fencing in the Princess Bride, watching that movie could be an esport.
