I agree it is a gap. I am not sure this is the best way to fill it, but if it is the ONLY aicraft filling it, it is very likely to sell well. Piper should be quaking in their boots about the Meridian... and I know a few owner-pilots (ok, two) in the TBM bracket that would definitely give it a good look!
Also, Cirrus has proven in the past that they can sell their aircraft into new segments, the SR22 outsold the competition considerably, and the SR22TN in particular has left the direct competition (Corvalis, Mooney Bravo / Acclaim) dead in the water.
I still believe a TP is a better TECHNOLOGY choice than a jet in that segment (just look at the figures - a TBM850 achives 0.72NM per lb fuel at 6,300lbs weight and 320kt, Cirrus claim 0.72NM per lb of fuel at 5,400lbs and 300kt) but the difference is not significant enough to be a problem - after all, who compares a Ferrari and a Lamborghini based on their fuel consumption?
