it looks like red/blue is the final choice.
Would you rather we spend our time allowing for multiple-colored choice for luggage OR doing actual improvements, like supporting new airplanes days after release (see the example for the PMDG 777) and adding new features and making bug fixes ?
Yes, of course, having unlimited development resources, we could offer everything, but then GSX would not cost as low as it does ( it has been out for more than 18 months and ALL updates so far were always free ), so we must make choices.
And, as explained countless of times, the order of priority for updates is:
1) TOP priority to bug fixing. This because users that already spent money should be served before trying to look for new users.
2) 2nd priority is new actual features that add to the functionality.
3) Lowest priority to something that's just eye-candy with no function whatsoever, and choices of colors for luggage surely falls into this category.
