@VenomXXR pointed out the TS4 comp meant it could hit 35 with continued momentum (obviously it wasn't going to continue at that rate), but I could have envisioned a scenario where it touched 30 following amazing reviews, its momentum would have been quite simply unstoppable.
Now it'll do... still great. Don't get me wrong, 20 previews is still fantastic, it's just not as ridiculously huge (Titanic-level) that people were hoping for. Should still easily pass BatB when everything's all said and done, and potentially reach Jurassic World. Mostly in line with what the average predictions were to begin with.
