I highly doubt Apple will try to cater to the amature film maker wanting to film their episodic adventure series. They don't even cater to Mac Pro users as they once did.I think if some is using their phones for 4K media production more than anything else 512GB storage is not overkill. Remember most people do not "talk" on their phones anymore rather they use text, social media, Skype, etc. With advances in photo/video technology the iphone is literally a portable media production center fully capable of producing an episodic adventure series.
