..my take on this
The M9 will not be replaced anytime soon. It is very reliable, user friendly, and worth every penny the DOD has tossed at it. If you have seen two fail, you need to hem that armorer and 3rd shop from the tallest flag pole. I have fired tens of thousands of rounds through the M9 and M11, and had 0 failures that could be blamed on the weapon. USASOC will do what they want, just as it always has been with them. They are not held to the "standard issue" weapons due to their mission and needs. When it comes down to it, they use what they want. If the DOD does choose to replace the M9/M11 with a .45 it will not be the 1911. The 1911 is a dated design. While it is great, and fun to shoot, it is not what is needed now. I think they would go with a .40 over the .45 anyway. And lets face it... short of directing traffic and weighing down a thigh holster, the pistol is damn near worthless in our current wars (Afghanistan and Iraq)
The M4 is much more reliable and accurate past the 350yrd line. There are a ton of soldiers out there that can constantly hit the 400m (437yrd) with iron sights shot after shot. An M68 or other optics make hits further.
The M60 was not a SAW, it was a LMG and now replaced by the M240.
The M249 (SAW) was built to replace the M16a1 for the AR in the squad. The M249 is now being issued in the "para" format, with a shorter barrel and telescopic stock. It has it's place, and like the M9, is not going anywhere soon.
The M14 is being dug out of mothball for as a DMR, not an entry weapon. I am sure there are some SOC guys running the chopped down versions, but they are the exception not the rule. 90% of all M14's down range now are NM's being used to provide longer range, more punch, and faster second shot than the M24 or M40A1/2/3. Much like the SVD and PSL extended the range and accuracy of the AK47 wielding commie, the M14 extends the range and accuracy for the M4/M16a2/4 wielding American soldier.
If you want an entry weapon, grab the M500... nothing else.
