I am not too keen on a Xenoblade Chronicles X port to begin with. I would like to support the franchise but given I already put hundreds of hours into the original version, unless they have something quite impressive to distinguish it I know I won't be buying it and I am not sure how many other Xenoblade diehards would give it a shot either if they already have the original.
I doubt they are going to do anything in regards to the story or ending, so at best we might see improvement on technical issues that plagued the original like pop ups, bad font size and maybe clean up issues where the mission radar is impossible to understand where the objective is located.
