The Android-powered mobile gaming device was scheduled to go on sale on June 27 but the retail launch has now been rolled back to "sometime in July."
According to Nvidia, the decision to pull the portable gaming console is due to a "mechanical issue that relates to a third party component."
Despite the fact that the chip manufacturer was about to enter an already crowded and hotly contested marketplace with its first offering, expectations and media attention have both been high for the device, since it was first revealed during the run-up to this year's CES in January.
The controller, which will have to compete with Sony's PS Vita and Nintendo's DS as well as any number of flagship Android phones and phablets, boasts some serious internal specifications including a quad-core Tegra 4 processor, a 72-core GPU, 2GB of RAM, 16GB of internal storage, a microSD slot and Android 4.2.2 Jelly Bean. What's more, under its 5-inch 720p HD screen is a full-sized games controller.
But the Shield's unique selling point or killer application is that as well as being able to download games from the Google Play store (just like any other Android device), it can also stream games from a computer and is calibrated for use with Steam's Big Picture mode, meaning that it is compatible with a host of high-end titles including "Assassin's Creed III" and Android games like "Cut the Rope."
However, this compatibility comes with a catch: the computer from which the Shield will stream will have to be running Windows 7 and have at least an Intel i5 processor and a Nvidia GTX 650 graphics chip.
Although the launch date has been pushed back, Nvidia is still accepting pre-orders for the Shield, which will retail for $299 when it is finally released.
