The original generation Xbox 360 was plagued with the dreaded Red Ring of Death when it overheated. Now it seems that the newly released version comes with the warning message shown above. Hey, at least the tell you that they made a console with crappy ventilation.
The message should at least stop them from getting flooded with units being sent back for replacements. You modders and DIY enthusiasts may want to drill some extra ventilation holes in that new Xbox.
