Yes, we will be porting our LINQ-based data engine to SL as the grid depends on it :-). The engine uses LINQ to objects, and we have no plans on coupling it to ADO.NET Data Services. Maybe we can provide some way to plug data services or something like that -- can you expand a bit on the usage scenario you are after?
As far as the Carousel control port for SL is concerned, we do not have a timeframe yet. The focus will be mainly on the grid control, and we plan to turn our attention to the carousel once the grid is running smoothly on SL.
All the best,
the Telerik team
