ViewSonic is lining up a new 7-inch Android tablet for launch at Mobile World Congress 2012, a source has exclusively revealed to Pocket-lint.com. 

The new tablet will be launching on Android 4.0 Ice Cream Sandwich and will feature a high resolution of 1024 x 600 pixels, giving it a pixel density of 169ppi - the same as the ViewPad 7x we saw back in August 2011.

We don't have any images of the new tablet, other than the artwork above, which must be a work in progress because one of the ViewScene 3D pages shows a "photo of the day" from "Flicker" (girls in bikinis too, naughty, naughty).

Although the tablet will come with the ViewScene interface, as we've seen on all recent ViewSonic devices, we've had it confirmed that it will be a Google-certified device, so you'll get all the normal Google services and Android Market access.

Our source says the tablet will be "ultra light", but other than that we have no details on the design. If the image above is the new tablet, it looks to have a squarer profile than the ViewPad 7x. 

We do know that it will be equipped with mini HDMI, Micro-USB and Mini-USB, which is something of an oddity. There will be cameras on both the front and back, we've been told that the rear will be 2-megapixels, setting the specs slightly below the ViewPad 7x.

There will also be a microSD card slot, so you can expand the memory over the 4GB that it ships with. We don't know what the processor is, but we do know there will be 1GB of RAM, so we'd guess it is a dual core processor of some variety.

We're told that this tablet will also offer 3G connectivity, which we guess is behind the G70 moniker, but otherwise, the name doesn't reveal at what level this tablet sits and our source didn't disclose a price.

However, we've found the ViewSonic G70 listed online and it looks like the price will be around $350 (£220), so looks to be good value for money.

Of course, nothing official has been announced by ViewSonic yet, but we're excepting a full reveal at Mobile World Congress in Barcelona next week.
