The new Roku 2(4210X) is basically a Roku 3.
That model is a R3 but shipped with a standard IR remote instead of WiFi Direct gaming remote. This was done as a way to strip down features and costs. When released, it was before the current lineup. It was meant to be: Roku 1/SE, Purple Roku stick, Roku 2 (stripped down R3), Roku 3 with built-in Mic and Roku 4 for that season of released hardware.
