Looking to buy a PS4 and Upgrade to an Xbox one S

So I'm looking to get a somewhat good deal on the PS4, extra accessories would be nice but not required, non exclusive PS4 games I want to avoid since I've played it already on Xbox One like XCOM 2 for example. I read that Sony won't honor the warranty if the console is not sold by an authorized reseller? Not sure what's that about and if I should be concerned when making a purchase for the PS4

I'm looking to upgrade to an Xbox One S, I've also played most exclusives for this console and it's non exclusive games like FFXV, if there's a good bundle/deal out there I wouldn't mind trading the extras in to GameStop or Best Buy, etc.

Please help me Just want the most bang for my buck.

Final note I will be trading my 1 TB XBox one S to GameStop by Sunday. I want to upgrade because of the smaller console and I need a newer controller. I have the elite console if that matters. Space is not a factor in the Xbox console as I have 2 external drives. Thanks again

If you have power up pro you get an extra $50 for your console. The deals are listed on the trade section there. So you should be able to get 160 for your console. I also wouldn't trade in your elite controller since there not giving you any extra for it compared to a regular 1tb system.

Can you just wait a few more months for Scorpio?
