There is no way that Microsoft will do the incremental numbering because they will always have one generation less than their main competitors (Sony). That is why they named the second Xbox the Xbox 360 and not Xbox 2, since 2 is less than 3 (PS3). The same reason why they didn't name it "Xbox 3" when they are competing against the PS4.
The best name out of what you listed would have to be Xbox Infinity.
