I hope by new character they mean new present time character....I don't mind Connor. It's Desmond and all his sections in every single game I can't stand. Unless the "new time period" is the present and the "new character" is a Desmond Miles that is actually enjoyable to play then I'd be cool with that.
But I'd rather see more Connor than do more boring platforming as Desmond in order to find a battery or something else completely lackluster. The best thing Desmond has ever done throughout the series is jack into the Animus, no more no less.
