Even if it does come back, you can't turn back time guys. BC2 was special, but because of when it came out. Things have changed, games have advanced, tech has advanced.
BC2 hooked me on the BF series. 1000's of hours later, DLC, expansions, BF3, BF4,BF1, and season passes I am ready to give Dice my money for the next game. But a BC3 will be a bad company game in name only. They captured lightning in a bottle with BC2. And it was really the map design and Rush gameplay that made the game, the people who did the work probably aren't even with DICE anymore.
I think if they release a BC3 it should be a spin off. Either make it the rumored Battle Royal mode, or a RUSH only game. Even make it cheaper or F2P (with microtrans).
BF2018 needs to continue what BF3/4/1 have been doing. Conquest, Operations, 64 players, vehicles, infantry all the good and crazy stuff that goes into a BF game. I don't want the game going backwards. BC2 was only created because PS3/XBOX at the time couldn't handle a full on BF game so they pared it down. Today's systems don't need to cut player counts or map sizes.
