I don't get why this is considered a dumb thing to point out. My post was straight up deleted so apparently that's taboo to mention here, but you'd think a site supposedly about "mac rumors" would know better...
Calling it "the next iPhone" or "the new iPhone" would just be too hard, I guess? It's asinine.
Not like any of the other comments here are any more insightful anyway.
I agree. Also, there is another reason it won't be called "iPhone 5" aside from the fact that Apple seems to be moving away from the version number being in the name. It won't be called "iPhone 5" because it's the SIXTH generation iPhone. Therefore, even if they keep the version number in the name it'll be "iPhone 6". I can't believe how many people forget this.
