They will continue to improve this over time. But keep in mind, all you can ever really expect is 1:1 performance with only one App open, that's a fair comparison. You don't compare performance on computers with one computer running several apps and the other computer running one before benchmarks are taken.
If it were possible to match or beat iOS scrolling performance while multitasking, Apple would have done it already.
