I love my e92 m3 - but would still tell you to get the M4. newer is always better. if you had asked ,back in the day, whether you should get the e46 M3 or wait for the e92 everyone would have told you to get the e46. there is always a bias towards the known over the unknown, the seen over the unseen. the fact is every successive generation of the m3 has gotten better. there's no reason to believe that wont be the case with the M4. you will have a new body style, with more powerful performance and more modability if you're into that.

personally I'm not a big fan of driving old body styles when there is a new one out.

unless you can afford to do both - get the current gen AND next gen - I would wait for the M4.
