Same as always with these questions: sort out your priorities and you'll have your answer. Polling is never the way to determine these things. Which is most important to you? The answer will vary from person to person.
If you're still unsure then the odds are you can wait. It's just that you don't want to. Still, your call to make. You're the only one that knows whether or not you'll be suffering from buyer's remorse when the new model is released or if you'll be happy with what you have since it suits your needs/wants. Again, each person differs and you have to assess this for yourself no matter how many opinions you collect. If you really want opinions then refer to the countless prior "Should I wait?" threads.
