All of your poll choices suck so....
Guess #1:
Xbox 5
That's it. No more crazy names as they move to numbers only. They'll skip '4' because they'll argue the 'X' was a major power version and this will allow them to catch Sony in the number game.
Guess #2:
Xbox 4000
Get it? 4K. O_O
Guess #C:
Xbox Infinity
Think about it. First they had 'Xbox' which we all would consider Xbox "1" had they used traditional numbering scheme. This was followed by Xbox 360 which could also be considered a circle (360 degrees). That was followed by ... you guessed it, Xbox ONE! So now they will repeat the pattern with something similar but not identical to '360' a circle or ... infinity. :) The marketing will focus on the infinite power this machine has due to streaming focus of its gameplay as it will use the power of the magical cloud. They'll also re-introduce the all digital concepts of the One but in a manner that learns from their previous lessons of people who still want physical shit. Xbox Live will have tiers similar to game rental companies but the rentals will of course just be digital copies.
Say it with me... Infinity... XI.
