Difference between CR XI dev R2 and Visual studio 2010 CR

I have been working upon CR XI dev R2 which supports 64-bit application in 32 mode only. Now i want to switch to Visual Studio CR2010 to make our application a full fledged 64 bit application. So for upgrading from CR XI R2 to Visual Studio CR 2010 what features will i have to compromise. or i will put it this way " will CR2010 be worth enough (apart from being 64-bit) and does it supports all the features provided by CR XI dev R2"

Thanks
