Here's a pretty cool frame by frame breakdown of the trailer.
I'm also optimistic but there's a rumor out there that they're gonna reveal it was Trinity who is The One and back burner Neo, similar to the treatment a lot of legacy characters have been receiving in reboots of late. I'd have no problem with a female lead and might even buy into Trinity as being The One all along, but I'd sure hope they handle it right and respect all of the characters. If it's more ham-fisted, preachy - make a mockery of Neo just to elevate Trinity bs I'm gonna have a problem with it.
It's only a rumor with zero evidence to back it up tho so I remain optimistic. Watching the trailer it almost looks like maybe it's Neo and Trinity together that might be the key to unlocking everything. I definitely wanna see more. I can still remember seeing the original in a theater when it first came out and I was pretty blown away. I wish every theater experience was like that one.
