Bethesda Softworks - After their performance of the past year, I'm not interested in anything Bethesda has to offer. They will likely just be talking about Fallout 76 updates and DLC.
Devolver Digital - I heard they showed up out of nowhere last year and had a pretty entertaining conference, but their games have always been hit or miss for me, so its 50/50
Electronic Arts - I'll probably watch it just to make fun of it. Last year's was awful and I doubt they have any hidden showstoppers to reveal.
Limited Run Games - Wait, these guys have a conference?
Microsoft - They will no doubt have something interesting to show off, but it would be lying to say I will be watching.
Nintendo - The company with the highest expectations this year, of all things. Animal Crossing, Smash Bros DLC, Luigi's Mansion 3, Pokemon, everything else. I'm a Nintendo fan above everything else, so I'm most excited for their presentation, and this year is looking to be their best in a while.
PC Gaming Show - I just remember this being forgettable every year minus one or two big games.
Square Enix - I don't really know what to expect from these guys besides more FFVII news.
Ubisoft - Unless there is a new Rayman game, I don't really care about what they have to offer.
