Ninty already started bundling MK last Xmas. The bundle, unlike the other ones, included WS, but not WSR and it was the second most expensive bundle after the BB and WiiFit Plus one, but it was already under 200€ (in EU) for Xmas and dropped to as little as 179€ after the holidays.
A bundle dropped to 149€, but with WS removed, could be perceived as a false discount, as value was removed together with the price drop.
Moreover, while WS already did everything it could to push Wii, and it did it in an excellent way, bundling WSR with every Wii bundle, even better removing WS from some, would be the minimum vital effort to push WiiMotion Plus and WiiMote Plus, that lack other best selling games besides the bundled WSR itself. If Nintendo starts pushing precision motion control even less than now, it will be like offering PS Move another chunk of its market for free, without fighting. Not good for Nintendo, neither for the industry, nor for the users, but nor for Sony itself, as it isn't pushing Move as it could, so possibly receiving for free a chunk of market for it, without having to develop more to consolidate it, could give it an ephemeral success followed by a fast withering.
