Macbook 2012 or wait for 2013??? Is there a touchscreen MBP in my Apple future....

Dear Apple Corists,

My PC is on the fritz and I would like to finally move to a macbook. It has been several years in the making, mainly monetary, but I am officially ready to purchase an MBP. Due to the wait and the investment, I would like to make sure I am making the right choice.

To be honest, I could care less about having a retina display. However, the one thing I don't want to miss out on in purchasing a 2012 model is a touch screen 2013 MBP.

Does anyone know if there is any chance of this happening? In addition, is there anything else groundbreaking that we can expect from the 2013 models or will it just be a spec bump?
