PC World - Firing a precision-control salvo at Sony and Microsoft's upcoming motion-sensing products, Nintendo says it'll upgrade its Wii sales pack to include the Wii MotionPlus snap-on and a copy of Wii Sports Resort, effective May 9. Those "upcoming motion-sensing products" would be Sony's 'Move' and Microsoft 'Natal', which we'll hear more about in June, and hopefully see firsthand when the holidays roll around.
