But I really don't see many improvements on the Shield thatare needed, besides the mag spring issue!
I plan on buying a shield using a gift card to Bass pro that I was given, but now I might wait to see if the 2.0 does come out.
Actually, more like accelerated obsolescence. Not necessarily in the meaning of them no longer working or being worn out... but just that it is so easy to make changes in injection molded plastic and stamped metal that it almost becomes necessary for marketing purposes alone so you don't get left behind. If the competition is changing, you must change too or get left behind and watch sales suffer. 
My old Shields are worth practically nothing now just because new ones are on the way! "Old" ones have been blown out with huge rebates to make room for the new (which will themselves be blown out with rebates someday before ya know it). 
One nice thing about all-metal guns: You don't have to worry so much about them going obsolete on you tomorrow... since them young whippersnapper folks already think they are obsolete today! 
No gun is obsolete that still is capable of performing it's intended purpose. That being, firing a bullet and striking a target where the operator intended and repeating the process without stoppage. That being said, younger folks must have the latest and greatest. They spend more on cell phones and calling plans, than us oldsters do on car payments!This is one of the major problems I have with modern disposable plastic wonder guns. Planned obsolescence.
Yes, I know it's a different world today. Things happen fast. There is always an "improvement" (or at least a "change") to be made. Take a look at the smartphone industry to see how quickly what you bought today will be obsolete tomorrow.
And yes, I am old and living in the past... a traditionalist.
