Google sent out invitations to an event at which it will take the wraps off the newest version of its Nexus 7 tablet, according to the Associated Press, which reported that the event will likely be held next Wed., July 24, in San Francisco.

The event will be hosted by Google exec Sundar Pichai, who leads the search giant's Android and Chrome operating system efforts.

The Nexus 7 tablet, which was released last year, has proven to be a popular and affordable alternative to Apple's pricier iPad. You can currently buy a Nexus 7 for as low as $149, while the iPad mini, the cheapest current version of the iPad, retails for $329. It'll be interesting to see whether Google simply introduces a refreshed Nexus 7 or whether it will release multiple Nexus tablets aimed at various markets and price points.

What do you think of Google releasing new Nexus 7 tablets? Are you surprised? Why or why not? Do you like the Nexus 7? Why or why not? Is it better or worse than the iPad and, if either, why? What do you want to see in the new Nexus 7 tablets? Sound off in the comments below.
