Yes, the @ built-in pointer is being removed as special, replaced by library types like Rc and Gc (for reference counting and garbage collection respectively). There's a vague suggestion for ~ to become a library pointer too, but I don't think this has been totally accepted by the core team. (This would leave only raw pointers and references actually defined in the language.)
There are some plans related to simplifying how vectors and trait objects ("dynamically sized types" or DST) interact but I don't understand them well enough to be able to explain. :)
