Update: In a Twitter post by Microsoft's Jacob Rossi, he stated, "We are not building a native ad blocker within MS Edge, but we will support third party ad blockers like AdBlock and AdBlock Plus".
Microsoft has big plans for the Edge browser in Windows 10, including the addition of built-in ad-blocking, the company revealed in a Build 2016 session today. As shown in the below roadmap of planned upcoming features and improvements, built-in ad blocking is targeted to appear in the next version of Edge (via ZDNet).
Ultimately, this could negate the need for certain ad-blocking extensions, such as AdBlock Plus and the like. Interestingly, extension support appears at the top of the planned features list as targeted for the next version, meaning we could see both features land for the general public at the same time.
The slide also provides an interesting look at some other bits that Microsoft is looking at bringing to its latest browser, including Bing Translator integration, swiping to navigate back and forward, and more.
