Amazon bundles PS Vita with free Gravity Rush game for US customers
But memory card still not included

The Pocket Gamer Silver Award-winning action puzzler Gravity Rush is easily ranked as of the best PS Vita titles available, but many gamers have yet to experience it.
Most likely, this is because they don’t own a PS Vita.
Amazon.com has stepped in to help remedy this oversight by creating a Gravity Rush PS Vita bundle for the lucky gamers who happen to live in America.
From now until August 4th, purchases of a wi-fi-only or 3G/
wi-fi PS Vita through Amazon will be eligible for a free copy of Gravity Rush and a screen protector two-pack.
While the cost of a PS Vita is still a bit high, receiving a free game and some gratis screen protectors (~$40.00 in savings) is nice way to make the potent handheld system more appealing to potential buyers.
