10 is the new 6

Raymond Chen

While it may no longer be true that everything at Microsoft is built using various flavors of Visual C++ 5.0, 6.0, and 7.0, there is still a kernel of truth in it: A lot of customers are still using Visual C++ 6.0.

That’s why the unofficial slogan for Visual C++ 2010 was 10 is the new 6. Everybody on the team got a T-shirt with the slogan (because you don’t have a product until you have a T-shirt).
