Should I Wait for the iPhone 5?

I was wondering if I should wait for the iPhone 5 that may or may come out in October or just give in and get the iPhone 4S. Here's my dilemma. I've been using this Android for about two years now, and to be blunt, it sucks really bad. The battery life is incredibly bad, and the phone is ridiculously slow, unresponsive, and quite often freezes on me. Taking phone calls and composing text messages at times has been a struggle. I really want to wait for the iPhone 5 but, I don't think I can take this Android any longer and I'm tempted to just settle for iPhone 4S IF, and only IF I have to wait untill October for the iPhone 5. I hope it will come it in the Summer, but I heard its pretty doubtful, what say you?
