I hope it does have ray tracing at launch, but I'm actually not bothered anymore. I'll just wait until it's fully updated. I decided a long time ago I was not buying Halo Infinite day one, and that's from a Halo fan that bought and owns every collectors edition up to and including Halo 5. There has been too many disappointments with 343i. I'll be waiting to see if it really is worth it this time.
Also, it's worth noting that this applies to a few studios and not just 343i, I don't see why I should back companies with my hard earned cash if they don't release a complete game. Many coming titles are a wait and see as far as I'm concerned. My friend messaged me and told me he's getting BF 2042 day one after the release trailer that showed zero gameplay, at least wait for gameplay.
