I think there is a hint of strategy here. Bolt was on last-gen tech for GM and killing it made sense to consolidate to the current-gen "Ultium" platform. There's just a lot of timing questions about GM not announcing a proper Bolt successor before killing it.
Also, favoring trucks is quite probably GM worried about Ford's massive US truck fan base and hoping they can outpace Ford's supply chain bootstrapping issues with Ultium, which did have something of a head start (and multiple proven predecessor generations). (It's interesting to compare Ford's stop gap F-150 Lightning/Mach-E on an already announced dead platform and Ford moving to VW's relatively more proven MEB platform as an attempted short-cut around supply chain issues by leveraging VW logistics.)
But yeah, I wish GM would finally announce the remaining "unknown" Ultium models and hope that at least one properly fills the hole left behind by the Bolt.
