Well in that case you are paying for a finished product and there would be reason for concern but that 4 GB is probably just being used up by operating software : ) You bought a ticket into their world that will be forever changing.. it is not a finished product but arguably the greatest idea in console history thus far. I'm sure there's good reason for them not releasing those exotics. They don't owe you an answer. Take a step back and look at the bigger picture from a development standpoint and not a consumer.
