A few things to point out... is that you want another VC6, because it was really that awesome. It was released BEFORE the C99 standard, so it wasn't required to implement it. Maybe you should connect its awesomeness to the fact there was no need for true standards compliance at that time, and that each VS has just been downhill from that.
Ragardless of how much logic or business problems you try to back up our lack of support for the past standard and implying why you also don't want to support 98% of the new standard, I believe to be a VERY horrible idea. In order for Visual Studio and the Compiler to match the awesome factor that VC6 used to be, you will NEED to have at least 92%-98%standards compliance unless it DIRECTLY destroys backwards compatibility without some sort of work-around.
I don't care if you need to make a "Standard Compliant" build of your compiler just for this purpose but you MUST play nice with the rest of the developer ecosystem which is the "black matter" of all developers, otherwise you will always be getting flamed about such things for something I believe you can indeed fix. I want standards compliance more than anything Microsoft can deliver when it comes to their compiler. I don't mean to sound demanding or greedy but I WILL continue to use both VC++10, GCC 4.6 snapshots and even Intel's ICC C/C++ compiler just to have those standards compliant implementations. Now that Visual Studio does have a standard which to worry about supporting, unlike when VC6 was born, I believe to give the prior beauty back to the VC++ compiler and even IDE you will seriously need to hammer down on trying to nail compliance as one of your top priorities.
Those standards bodies are around for a reason, and have also put an MASSIVE amount of resources towards developing such standards, so as they are a master of their standardsation craft, others are masters of their own. But they took ~10 years of planning and hardcore industrial work just as you have, to create the standard known as C++0x which I believe was made for a purpose. There are some pretty joke standards and informal standards out there I do agree. But imagine a huge swarm of Stephan T Lavavej's working day and night for a decade on this new standard, its not exatly a standard which was jokingly created or full of coin-toss decisions. They have credit for their profession, and truly considering their decisions in todays world which C++ WILL pave the future of computing, merits more than just business constrains for deciding to do their job for them and picking apart their master carved standard as piecemeal features.
Therefore, consider those release timings of the C99 and VC6, opinions of many desiring the features which are in C++0x, and the reasons people even decide to use a different compiler so that you can try to attract people back to allow 100% usage of VC++ while on the Windows platform.
Just to clarify though, I did immensely enjoy this video, he is a pretty cool dude. I just tend to really be direct with my words hoping to provoke thought and constructive conversation even if I'm not correct 100% of the time .
