We reported yesterday that Sony will release a special limited edition PlayStation 4 during the PS Experience.

To further expand the festivities, Sony has released special themes for the VITA, PS4 and PS3.
The background for the PS4 has been changed to light grey, while the icons have been changed from their sterile blue to a white background with colored stripes. The start-up tune has also been switched to the PS One’s old tune. If you stay idle for a long time on your PS4, you can hear a mixture of the PS2, PS3, and PS4’s music in the background.

The VITA has almost the exact same setup. The music is reminiscent of the old PS2 theme / PS3 and a bit more VITA theme thrown in to the mix. For some strange reason the PS One’s music is absent from the Vita theme.
Still it’s a nice gesture from Sony to add these extra themes for free.
