Wii MotionPlus Out Pre-June 18

Word on the street has it that Nintendo’s latest motion controlling add-on, the Wii MotionPlus, will be out sometime before June 18. After all, it would be wise for that to happen before the Grand Slam title is released since the game ought to push sales of this peripheral by a fair bit as folks continue to search for a more interactive gaming experience. How much are you willing to fork out for the Wii MotionPlus, and if you’ve purchased previous accessories for the Wii already, how do you rate those? Are they favorable enough to warrant future purchases from reputable brand names, or do the vanilla Wiimote and Nunchuk work for you just fine?
