Go to the entry level luxury ('executive')? Lexus, Acura, even Cadillac all have hybrids, with outright electrics planned over the next year to two (and despite pre-orders being available soon, it's not likely we'll see the 3 before 2017 - and that's only on the west coast; good luck getting an 3 in PA before 2019 - and as soon as you do see a firm delivery date, all those other manufacturers now have a concrete target to aim at).
It's not all a matter of "well, the S sold well, so the 3 will conquer."
Not even close.
