Finally, there is a couple of features that were added to Objective-C since then that should be added to the todo list to keep feature parity. Some of those, if implemented right, could benefit the rest of D too. For instance: ARC (automatic reference counting) which is becoming a must in Objective-C.
Arc has very serious problems - I don't see how it can be done and be memory safe without adding extensive pointer annotations. The general problem is someone taking the address of a member of the reference counted object. The rc goes to zero, the objects gets deleted, and there's that dangling pointer to it.
