I'm not surprised though, since they have Moore on the team and I think they did something similar on PS2 launch. I think is job is to make aius many parallels between Xbox360 and Dreamcast as possible.
No, just certain people feel compelled to connect the two as much as possible for alterior purposes. I have already posted at length on the nonsense of the Dreamcast connection and how people can easily draw other superficial comparisons (like N64/PS3) that only meet a users immediate need and lack any substance.
I see no need for the constant DC "hints" and connections without a substantual examination of the markets and (dis)similarities.
