Probably the 'conference' with the least relevance to PC viewers, but at least it will bring you joy. Nintendo's E3 2017 spotlight event starts at the top of the hour, with 25 minutes of cutesy, Switch-bound content expected. In the past we've seen things like Wargroove debut on Ninty's dime, and the same could happen again.
Not convinced? Have a look at all the things we've discovered at E3 2017.
There are also various companies that haven't said hello at E3 yet - Rockstar and Square Enix come to mind - who might have given their multi-platform debuts to Nintendo for that extra punch.
Alternatively, all this wishful thinking is for nothing and you'll end up watching 25 minutes of pleasant videogames for absolutely nothing. What a tragedy.
