A long while ago rumor was that Google was in talks with Asus to contract out a "Nexus series" tablet. Google has been saying that they want to expand the Nexus devices to maybe having tablets and multiple handsets per generation. Supposedly they're going to release 5 Nexus devices for Android's 5th birthday and its been suspected that a tablet will be at least one of them.
The only problem I see is that if there is too many nexus branded phones/tablets made by different manufacturers. Its going to get very confusing for the consumer. I would like a cheap but decent tablet. These tablets today are just a rip off in my opinion.
