No they don't need to be retro pixel-art sprites, but games need to stop taking the easy way out and using 3d models instead of 2d art.
Rayman Origins and Legends show the effort that should be put into the graphics of 2d games. 2.5d is a mistake in almost all instances and is just done because it's quicker/cheaper.
