Dont know how you feel about the hard drive in the xbox one, but I personally think that the hard drive should of been at least 1 TB and not 500 GB. I also wonder why they made it so the hard drive cant be taken out and upgraded like you can with the 360. I know that eventually you will be able to hook up a external hard drive, but not at launch so hopefully sooner than later. The 500 GB would be fine, but from my understanding if you buy the games on disc they have to be installed and from what I have read online the install gaming sizes are in the 30 to 50 gb range. What do you think? Also take into account that 4K television is in its early stages and with that comes 4k blu ray disc that can hold at least 100 gb if not more and my thinking is in the future we could see games in the 100 gb or more. Killzone Shadow Fall for the PS4 is 290 gb before they compress it down to 50 or 40 gb just to give you an idea of how big the games are already.
