Be surprised! They won't redesign the wing. I'd wager a cold one on that.
What's the point speculating on an accident where we don't really know what happened and why. The NTSB will issue their professional opinion so that we may learn from it.
If you have a personal preference to Piper and Cessna aircraft designed in 1950, please keep flying them.
Let those who believe there has been some progress since, enjoy the new stuff. You may be aware people get killed in other brands as well, regardless of their 50-year history. Sometimes it doesn't have anything to do with the aircraft.
Icing conditions, as any pilot knows, is very bad indeed. Aircraft sporting boots, heated leading edges and TKS icing all suffer from the same problem. If you can't get rid of the ice, you go down, fast. I'm sure the TKS deice system on the Cirrus fleet is intended to aid your escape from icing conditions, just like on any other aircraft.
Doesn't help if you're in a Caravan, ATR-42, B737 or SR-22.
