Kendo UI for ASP.NET MVC will have a .NET 4.5 and ASP.NET MVC 4 build when there is need to. So far we haven't implemented any ASP.NET MVC 4 or .NET 4.5 features. When we so so we will have a dedicated MVC4 build.
On a side note I couldn't understand the remark about the editing. Could you please clarify? Some explanation with the code you have used would definitely help.
