The way Microsoft likes to shuffle project teams, it's a bit of a ship of theseus. It's a very strange philosophical debate if the Edge team is the "same as" the IE10/11 team. The Edge team is definitely not the IE7/8/9 team, that I'm sure of. The Edge team can't possibly be the IE6- team, because that team was entirely disbanded. The IE10/11 team inherited the mistakes of the IE6- team by way of a need for backward compatibility and the backward compatibility plan put together by the IE7/8/9 team. Does that backward compatibility arc define what was the IE team? If so, then the Edge team is definitely not the IE team, having for finality killed the backward compatibility story of IE7/8/9.
