Also, this wouldn't be the first time they've had to retcon a weapon out of the game for a new class ;P

Paladins used to use "daggers" from time to time before rogue/ninja came out. Which was when they changed their name and replaced them with a new model of an actual sword.
The difference there is its daggers splitting from paladins not swords, this is pulling a polearm from a class that uses polearms to make another class that uses polearms. Is it possible that Samurai will also use polearms? Yes, likely? Not so much, especially because most people associate Samurai with Katanas.
