I think 343i is smart enough to name her something other than Cortana.
Her name could end up being Ana the last three letters of Cortana
I was reading about this earlier and it got me excited. “Joy” would be an awesome name.
the logical thing is to name her cortana. if they do anything else, they are dumb. Microsofts Alexa and Siri is literally named Cortana, they were never truly going to make her stay bad or kill her off. instead we got Cortana 2.0
Oh it better be Karen
There are also the simple Possibilities of her clone-mother Catherine and her daughter Miranda, but she wouldn’t have known about Miranda at the time.
Her name is Dustin Echoes
Well she had 6 months to think about it…
Or did she just come up with a name on the spot?
What is she running windows 11?
She’s obviously going to name herself Dustin Echoes duh 
I disagree. Just being a straight copy would suck and would be unoriginal. She may be a copy, but she’s also different.
She will be never called “Echo”, that’s 100% sure, not because it’s a bad idea, but the thing with “Echo” is that it could turn into a marketing thing in favor of Amazon for their Alexa speakers (Which you can even call them “Echo”), and we must understand that this is a Microsoft game, just an objective comment since this is a business.
