So this means Edge now right?
No.
...but is it correct that MS is now referring to Edge as IE?
Definitely no!
Or more specifically the new Edge?
Ummm, no again.
Do not confuse Edge with IE. IE is dead (kinda, sorta). Or at least MS wishes it was dead and is trying to forget it. I have not heard of anyone referring to Edge as IE - except, now you! Don't do that! You'll confuse me!

When Windows 10 first came out, it included a browser that was clearly half-baked - literally, an "unfinished" browser called Edge. It really was unfinished. Many of the features didn't work. It didn't support add-ons or extensions. It was bad. Really bad. It's only virtue was that it was pretty quick. Other than that, it was bad.
It was so bad, Microsoft totally abandoned it! Seriously! Instead, they decided to go with a totally new browser that was based on Chromium. Then they actually went into a partnership with Google so this new browser could use the vast majority of Chrome's add-ons and extensions (actually, that's a good thing). But instead of calling it a brand new name, they decided to follow Microsoft's tradition of using similarly confusing naming schemes. So they decided to call this brand new browser that was replacing Edge, and totally different from that old Edge, "Edge"! Makes sense, huh?
Unofficially, they call it the "new" Edge. But make no mistake, it is totally different from the "old" Edge and totally different from IE.
This is sort of like the original Windows Defender was an antispyware only program for Windows 7. But - when Windows 8 came out and later with W10, it included Windows Defender which was a full fledge anti-malware solutions. Two different programs in development at the same time with the same name.
It is sort of like, kinda sorta, but not really how there is an Outlook Express, Outlook and Outlook.com - 3 totally different email programs with very similar names.
Clear as mud, huh? If that makes sense to you, come back and explain it to me.
