I still hope Namco could bring Xenosaga HD Trilogy to Switch. I would take pretty much anything from Monolith Soft, as I know they are masters of RPG's. Maybe one day Square-Enix could bring Xenogears to modern consoles, perhaps with some overseeing from Monolith Soft to make it more player friendly.
All I really want is for the Smash character to not suck, more Astral Chain footage, and the Switch revision. I'm really only expecting Astral Chain footage to actually happen though. I'd love for Nintendo to really surprise and impress me but it's been years since that's happened so I'm not getting my hopes up.
I (potentially) spoiled myself on one announcement but other than that i'm completely blind (unlike last year) so i'm looking forward to what Nintendo will show. I hope we get a hype story trailer for Three Houses and more info on Luigi's Mansion 3, a Metroid Prime Trilogy reveal would be nice and more Astral Chain is welcomed.
My experience with Nintendo when an E3 hinges on them is.....not very good. Often they were more disappointing than all the rest of them when they had a clear stretch to the goal. But this time, they got a lot of good shit already in the cooker (Astral Chaaaaaaaain).....so we gotta believe.
