I see Nintendo leaving things as-is, at least for the time being.
If they packed-in both WS and WSR, it would be weird to have the redundant sports. If they replaced WS with WSR as the pack-in, it would be even weirder to have the redundant, inferior sports in a stand-alone package.
They could, potentially, include Baseball, Boxing and Tennis with a new version of Wii Play, and totally eliminate the original Wii Sports.
The opportunity to change the retail lineup would probably be if they ever decided to build Motion Plus into new controllers.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
