He's really old. He was never good at predicting anything to begin with, he just had a really loud mouth and made shock-value comments that got media attention. Not having Geoff Keighley's show to piggyback on with his segment was how he made his name in gaming circles, (and also annoyed the shit out of Reggie and others with his silly comments).
Without that dedicated airtime and making loudmouth comments, he's retreated back into just being a regular old dude. It's really not a super interesting story what happened to him, nor I would argue was he ever actually an interesting figure in gaming to begin with. He was like the Donald Trump of gaming. Extreme loudmouth, nothing actually productive to say, and very often wrong about nearly everything.

As we've seen for years now, being really loud with shocking statements gets you a lot of attention. But just because you can, doesn't mean you should. And if you haven't figured it out by now, the loudest people usually have the least to say.
One year I remember him saying Nintendo was fine on the console side with the new Wii U and super competitive on console, but completely toast on the handheld side with 3DS because of PS VIta & mobile. Well the Wii U was just about to launch and boy it is like literally the exact opposite thing that happened. 3DS is literally what carried Nintendo financially for four years while they had a state of emergency inside the walls of Nintendo from 2014-2016 to create the Switch and have strong launch year titles in 2017.
