Buy refurbished model now
Like many others, I don't think we'll see a significant improvement in the next iPod Touch - much the same as with the revamped 2011 model, very minor improvement over the late 2010 model.
As such, and if you wish to hedge your bets, purchase a refurbished model now, and if the updated model does not comply with past experience, you can sell it on at a good 'used price' and purchase the newer model in the final quarter.
