Dunno how many of you know, but Puerto Rico voted to apply for statehood. And I fully support the motion. I hope they do become our 51st state - and therefore, I have made a 51-star flag in demonstration of that support.
Not necessarily. Actually, what would happen is Congress would accept flag design submissions and select one design for production. That might be a potential design submission, but if you'd bothered to read the rest of that Wiki article, you'd've seen that there were a couple other 51-star designs in there too. So no. The design to which you linked is not the only potential 51-star design.
