3d vs 2d poll (Patreon)

Hi everyone! I just want to ask everyone on their opinions for how the game should handle it's change from 3d into adding new 2d character sprites.

Would you guys feel it's best to wait longer till all sprites are done before replacing the 3d models with the new ones in one update for the game?

or

Would it be better to add a new character sprite into the game asap, once completed but the other characters sprites will show as 3d ones till updated every few weeks?
