I think this is a nice future, for example look this code:
 
Dictionary< SomeClass, List < SomeOtherClass > > myDic = new Dictionary< SomeClass, List < SomeOtherClass > >();
 
We really need to tell the compiler in this expression what the type of myDic is?
 
This is more concise and clear at least to me:
 
var myDic = new Dictionary< SomeClass, List < SomeOtherClass > >();
 
If you are developing an application, you should know the semantic of the method, then the code
 var productsTable = GetProducsDataTable();  
should not be a problem, if you are just reading the code, check this out.
 
List<product> products = GetData();
foreach(var product in products)
// doSomethingWithProduct(product)
</product>
 
The no less readable code:
var products = GetData();
foreach(var product in products)
// doSomethingWithProduct(product)
 
I think this is dependant on the context. I'm completely sure that if you choose your methods and variables names well, the code written will be more readable.
