So the console says "ИС4" / "IS4" instead of "ПС4" / "PS4" because I guess "Play Station" is getting translated into Russian as "Игровая Станция" before getting abbreviated.
The upside-down cursive Cyrillic is too messy for me to make out anything but Katya's name and "SEGA". Maybe someone who actually knows Russian can take a stab at it.
