Cadillac considering 2.0l turbo 4-cylinder for CTS

In a move to get average fuel economy up across the board, GM is considering some interesting powertrain combos. The one of interest to us here at tCE is the rumored consideration of the 2.0l Direct Injection, Turbo 4-cylinder engine in the CTS. This engine puts out a stout 260hp in the Saturn Sky Redline, Pontiac Solstice GXP, and the Chevrolet Cobalt SS. The advantage is that, even with power equivalent to the current, non-DI 3.6l V-6, you could expect significantly better mileage. So, your thoughts? Would you even consider a turbo 4-cylinder CTS?
