I wonder if the PS4 Uncharted bundle is sold out because Amazon simply underestimated how well the PS4 would sell or because Sony is about to replace it. Simply replacing Uncharted 4 with Horizon would make sense IMO, Uncharted 4 is already over 1 year old and bundling in Horizon would be a great way to get people into the franchise before the DLC is out (that's probably somewhere in 2018) and people who like the game would obviously be more inclined to get the DLC and Horizon 2 on the PS5 (Horizon 2 being a PS5 exclusive is speculation on my part).
There is that gold slim coming out next week, they might be getting ready to push new bundles.
Yeah, maybe they'll announce some new bundles at E3, with some of them available immediately?
Also, seems that the CoD bundle is also sold out. It says "Sold by Above All Games and Fulfilled by Amazon".
