Yup, I fully agree. They won't want anyone to jump onto one thing or another.
As jpaige pointed out, don't hold too much with those comments. They are just guessing and throwing names out.
Just have to keep waiting.
Here is a different thought. Maybe the iphone5 may NOT have it, but what about the rumor of the "ipad mini"? Now that would be an idea to do. A lot of people would be using ipads and want something a little bit smaller. Use the backing with liquid metal to make it stronger and won't scratch as much, etc.
So, all rumors, speculation, etc. We may or may not find out during the conference, or we may find out for sure.
It would be nice if it would be used somewhere so we gain more exposure to gain more customers, so we will get more revenue and therefore profits. That's the big picture
