they should really do that. this is one of the most important things, to carry people from 360 to xb1.
just imagine people have a 360 and see more and more people in their friends list who have an xbox one. they will think "god damn i believe i have to buy that console as well anytime soon"
or when 5 people are in a party and one or two have an xbox one. they will obviously talk from time to time in this party chat about the games and the xb1 players will tell the 360 players to switch because it's awesome.
not to talk about those who want to buy an xbox one and are half the day in a party chat with their friends. if they can't be in the party with the same people when they buy the xbox one they will think twice about their purchase. party chat is for some people more important as the games on the console, seriously!
