Alyx was really good (though I'm a wuss and couldn't finish it) but not a continuation of the cliffhanger that we've been sitting on for 16 years since episode 2.
A decade ago, yes. Valve was riding high on the dual successes of Dota 2 and Portal 2, we were only 6 years out from HL2Ep2, and CS:GO was newly released.
Today, not so much. Aside from a prequel, the series had been dormant for as longer than it had been alive (11 years alive 1998-2007, 13 years dormant 2007-2020), and the prequel required a pricey hardware peripheral to run. It’d get attention, but it wouldn’t be that big of a deal at this point.
