Much as the reveal cinematic looks great, it still won't be my cup of tea.
I've been a CoD fanboi for a long time. I love its twitch, arcade-style gameplay, tight maps and scorestreaks, but like many CoD vets, I've become frustrated with the franchise over the last few years and would love a dev comp to step up and take over the reigns. I was hoping Respawn would do it, but they're focussed on BR, like many others these days. I can't see BF ever taking over from CoD, either. Battlefield is always going to be slower than Call of Duty, focussing much more on strategy, patience and vehicles than CoD, resulting in a very different experience. If BF were to try and emulate CoD it would lose its identity (just like Call of Duty has done in trying to emulate Destiny and Battlefield, etc.).
I might try it out if there's an open Beta, but I can't see Battlefield 2043 becoming the CoD killer. Unfortunately.
