I had some similar thoughts, so just bought my 2011 S4 off 42 month lease. Have 40K on the clock. CPO'd, new set of summer shoes (still have tread on my winter tires for another season or two). Thought hard about a S3, but just too VWish vs. Audi. The MT was important to me. If the '16 S4 has a MT, i'm all over it. Otherwise, my run of 5 straight Audi's is in jeopardy (but a torquey electric may catch my eye if in a Audi package).
