These are part of the stretch goals. I can't promise to give a version of the game on these, if these goals are not met!
Also, I can't guarantee 100% that the game will definitely be released on these, even if the stretch goals are met.
From a technical sidepoint, there's no issue at all : Game Maker Studio allows exports to these machines, and aside from some additional code to integrate specific functions (achievements, saves...), this won't be too much time-consuming.
But, this is up to Sony and Microsoft to accept me as an officially licensed developer!
However, I am pretty confident that achieving these stretch goals will make them interested, because this would show that a lot of people WANT the game!
In any case, I really, really want to see Demetrios on consoles, and will do everything possible to achieve this! :)
