Are those freakish yellow portly dudes just placeholders or is that would they are going to look like in the final release?
True. They could go Notch's route: Rake in millions of dollars from selling the shitty alpha/beta versions of the game while developing at a sluggish rate, then use that shyster-earned money to bulk up the development team post-release and THEN start adding in features that make the game slightly less boring.
Gonna go out on a limb here and say that you are not a big Minecraft fan.
