It's strange they don't understand that doing nothing but keeping the Pro up to date spec-wise would've signaled mild disregard already. Keeping it frozen for four years is a clear, prolonged, 'we don't care about you' message to pros.
And everyone could've told them the trashcan design made no sense, and in fact did when it debuted. No need to wait four years for that. Probably Ive really really liked it and nobody managed to stop him.
