Launched in a wave of excitement, it looks like Nintendo has underestimated the numbers it needed for worldwide shipments of the Classic NES mini unit. The £50 retro microconsole with 30 games installed is out of stock pretty much everywhere. So, no Bubble Bobble, Mario Bros, Double Dragon or other joy to scratch that retro itch. Virtual Console on the Wii anyone? They must be about the same price now.
