Only 4 New Features in C# vNext?

I've always admired the effort that Microsoft put into the design of C#. It's difficult to find the right balance between power and flexibility, and on the whole I think they've done an excellent job.

At the same time, it's been great to see the language grow, particularly with the addition of LINQ. As Jon Skeet has written recently, C# today is noticably more complicated than it was at version 1.0. Personally, I don't think that's a bad thing. The C# community has grown up along with the langauage, learning the new features as they have been released.

I can see this process continuing for some time, with the language continuing to grow. So I was suprised to see this comment from Microsoft's Mads Torgersen, in response to some suggestions that I posted at Microsoft Connect:
"We have to do some harsh prioritization, both because of our implementation and testing resources, but also because we need to keep the number of new langauge features at a manageable level - depending on how you count, we are adding only four language features to C# this time around".
We more-or-less know that one will be some form of dynamic lookup. That just leaves three others. They might be big "killer" features (like generics and lambda expressions in previous versions) but there's still only three of them.

I don't know what to think. Should we be trilled that Microsoft are continuing their excellent track record of keeping the language simple, or should we be dissapointed that there will be so few improvements?

I think whether or not this is a good thing will entirely depend on what the features are. Personally I think the dynamic lookup feature is a terrible idea, regardless of how it is implemented. C# should stay an early-bound, statically typed language. If I need dynamic lookup, I can always use VB.

Generally speaking I am fine with only adding a few new features in the next version, as long as that means that the next version will come quickly. If it takes another 3 years for these 4 features to make it into the language, that's too long.
