Has Microsoft finally given up on Internet Explorer?

A new report claims that Microsoft is planning to launch a completely new browser alongside Windows 10, but plans to keep Internet Explorer 11 around for “backward-compatibility’s sake.” Of course, that’s not very reassuring for remaining IE fans.

Many have speculated that Microsoft planned to greatly revamp its flagship web browser in order to better compete with rivals, but the company’s next big browser release, codenamed Spartan, “is not IE 12,” ZDNet reports.

What this browser will actually look like, as well as its final name, remains unknown at this time, but the product could debut at Microsoft’s Windows 10 “consumer experience” event on January 21.
