I have a question for Xbox staff. How much longer will it take to update website? Why Microsoft is updating payment system without the system itself done?! I'd understand and expect this from minor company which is not long on the market, but for Microsft is a big corporation! You should know better and provide quality services, you obviouslu don't. Please, update xbox.com and then start solving problems. It can't take a lot of time and more than few lines of code to introduce payments with Micrsoft account, and of you can't do it so easily, you should have not done it before the service is fully functional. This just make Microsoft and Xbox departament look bad. And you don't need this, Xbox departament seems to attract a lot of this "bad kind" of attention.
And argument "download from your console" is invalid. I cannot. Many people can't.
