I wish they would focus on:
1) Creating a single stack handgun
2) Creating some type of rifle
I like my Glocks the way they are.
Hopefully when the new model gets released at the 2010 SHOT show everyone will want one so bad that the market gets flooded with cheap used Glocks. :P
On a side note, it would be absolutely hilarious if these new Glocks have a magazine disconnect and external safety on them.
