He wasn't answering to the OP, but to the people making comments about why content gets delayed.
Reason for the delay being, since you guys are haing reading comprehension problems: it's better to implement stuff together than one by one, because every time you add something, there is a possibility that it will break something else. Once a pack of thing is well implemented and tested and proved mostly harmless it gets added to the game.
God is it so hard to read?
