iPhone 5 can not support 4G LTE

With the coming release of iPhone 5, IT and technology savvy people are guessing if it can support high speed 4G LTE.  My view is that iPhone 5 will not be equipped with 4G LTE air interface.  The reason is that there are now just a few 4G LTE networks.  Apple must make a logical decision and careful investment.  May be iPhone 6 released in next year can do that.
