I am not sure where I heard this, but I think I read someplace that AmEx credit cards only will allow you to have two points/miles promos per year. Is this true? In the summer of 2012, I received SPG points, and I am working on 50K points from a HHonors AmEx.

Could I open another card with Amex and get points, or will I be shut out until the summer of 2013? any ideas?
