It's definitely not over. You don't get a new form, one chapter of seeing it, then the fight's done. We got literally no historical context whatsoever around Snakeman, or the King Cobra attack, so Oda just ending it here and moving on is definitely not his style. I personally see another Rusukaina flashback, with or without Rayleigh where we get to see Luffy discuss/develop this attack in some kind of way.

I have to admit that I share some of your concern though. Oda has made it clear that Luffy is still inferior in Busoshoku Haki even in this new form, so why should we expect him to come out of  this clash on top? Is potentially superior attack power/force enough to overcome superior busoshoku haki?
