SeX.
But I'm going to wait for a Costco bundle so I got their indefinite return policy (consoles not treated the same as 90 day electronics). If it means I have to bite the bullet on a bundle where I have to buy it with an extra controller or pack in game, that's fine.
Might take me to next year as Costco Canada is lousy with console stock (both in store and online). Half the time it seems they don't even carry any, while only stocking up during holiday gift buying.
I like it having a 4k drive too because I have some 4k movies, but no dedicated 4k player. Xbox One X is my 4k movie player, so SeX will be too. I'll just get rid of One X somehow. Trade it to EB for credit or just give it to my brother.
