It's Thursday and that means new goodies to find in the PlayStation Store.

In the US and Canada the store has one new demo, Armored Core 4, for fans of the series to check out. Also available is the trailer for Grand Theft Auto IV that has GTA fans clamoring for more. We also have an updated version of Gran Turismo HD, which adds force feedback support and worldwide rankings. Finally, there are 3 new movie trailers- "Perfect Stranger" starring Halle Barry and Bruce Willis, "Are We Done Yet?", a new comedy movie starring Ice Cube and "Stardust", based on a graphic novel by Neil Gaiman and Charles Vess.

For the UK we have a new downloadable game, Super Rub-a-Dub, based on the rubber duck tech demos some may recall from the pre-launch PS3 press conferences. You can check out the game for free by downloading the Starter Pack. The full game is going for GBP 3.49. This game is currently slated to hit North American systems on April 26.
