It's hilarious how completely bias your opinions are, it's probably some sort of self rightous chauvenism that you see in Lightning being a representative for many generations of a franchise.
You truly believe that you know more than all of these people, that's plainly arrogant. Lightning having a game in production during the 25th Anniversary of Final Fantasy means nothing, coincedental timing is coincidental. If you even knew anything about Square Enix, you'd realize they already assume Cloud was their most favored character. The reason they aren't making a new game with Cloud as the primary protagonist is because they won't, at least not until they've toppled Final Fantasy VII's "Reputation". They're ashamed of themselves for not being able to create a better experience since then, and vow to attempt create; rather than finish what would gain them the most praise for their company.
I do not hate Lightning at all, however...
You have no place to be blindly casting your doubt over a person, character, or companies decision whether it be true or not.
Please, stop being arrogant.
Everyone has a chance, Final Fantasy has very memorable and beloved characters, if it is or isn't Lightning --- Deal with the aftermath respectively; because frankly it seems the people don't really want to care about your opinions anyway.
