So if i follow you correctly, you're selling your house, so currently you can't put anything bigger than what you have in your family room because of how you have your speakers setup.
So, in your new house can you have any size you want and that's when you'll get a bigger TV.
I don't think these LGs are going any lower in cost, $2600 is very low for the C7, I got mine earlier this year for $3300. I've seen the black friday ads for Best Buy, Target, and Walmart and they don't have these in there.
I've been eyeing this TV, which The Wirecutter and several other organizations have recognized as pretty amazing.
I saw one in person and was awe-struck. I have been hovering over purchasing one for approximately a week or two.
Don't even think about it, just get the damn thing. That's the exact one I bought a few months back, the C7 65" and it's absolutely incredible once you get it in your house. It's pretty much universally considered the best TV out at the moment. The colors are great, the black levels are totally unreal, it has very low input lag for games (21 ms), and it's totally future proof as it has all the standards you need (HDR10, HLG, Dolby Vision).
BF2 has become a shit-show for the BF community. Apparently the mtx has been taken to a whole other level and people are pissed.
What TV are you getting Tucker? Any 3rd party games will certainly look better on Xbox One X vs PS4 Pro. That's been the track-record so far for 3rd party games according to Digital Foundry. The only exception has been Titanfall 2.
