I don't think it's that terrible. At least, no where near as painful as the WiiU's final two years waiting for the Switch reveal where we got a serious zero news regarding anything. At least Sony has shown of games that are coming soon that look promising.
2 years before the Switch released was March 2015. At that point Splatoon, Super Mario Maker, Xenoblade Chronicles X, Pokken Tournament and of course BotW among others hadn't been released on Wii U yet.
What are you talking about?
