Just because a game is successful doesn't mean they have infinite resources. New space or servers for housing means more manpower, more time to upkeep them, more money, etc. It isn't really as simple as you seem to think it is. Not to mention how much of that is going into patches and expansions which should definitely take priority over housing. Housing is in high demand now more than ever so they had to find a solution sooner rather than later. Perhaps a better one will come along. We just don't know yet. For now this is fair and faulting Yoshi-P for something he said over two years ago when housing shortage wasn't an issue seems silly.
