Myself, again I feel correction of Glocks error in providing a platform to house several dissimilar calibers has existed and may now be an attempt to do so. There will be winners and losers with changes, but like the 9mm revolution most will remain. Ive never seen anything manmade get people through Life or a crisis that could outdo the equipment God had given them between ears. People can give homage to caliber and gun but the war of words of calibers does fall moot to many who see beyond the fluff. What may be the solution of the future already exists. Many have said the options in Glocks for carry might be a 9mm or the 29/30 platforms. The .40 and .357 sig might be too big or heavy an option. Time will tell.
