We saw this coming. The prices of older PS3 models (20 and 60GB versions) have doubled in Japan as their PS2 backwards compatibility feature becomes a sexy object of desire.
The PS2 backwards compatibility of earlier PS3s was scrapped in the more recent 40GB SKU as part of Sony's effort to reduce production costs.
Now, fearing that PS2-playing consoles may become somewhat of a niche, desperate gamers are snapping up consoles for up to twice their typical value.
20GB consoles, which previously sold for around 15,000 Yen in Japan have been marked up as much as 40,000 in some second-hand shops. The same shops are also giving premium cash back to those willing to sell off their full-fat consoles, according to Hobby Blog.
We're holding onto our 60GB consoles like precious babies.
