Hot Shots PS3 bundle cheaper than standalone console

What's the value of Hot Shots golf for the PlayStation 3? Apparently negative 5,800 yen (that's approximately negative US $47).

Siliconera has found a pair of Hot Shots PS3 console bundle, with the 20 GB model for 51,980 yen ($423) and the 60 GB model for 61,980 yen ($503), according to Impress Watch. And though on Amazon Japan, the 20 GB standalone model is cheaper at 49,980 yen ($406), the 60 GB standalone SKU is 67,780 ($551).

Is this indicative of a forthcoming price drop, a distaste for golf, a miscalculation, or some rift in the time-space continuum where a bundle of consoles from three years ahead found their way into Sony's hands? If that's the case, somebody check that Sixaxis for rumble.
