Google is gearing up to launch a new version of its Nexus 7 tablet in the second half of 2013 that could be priced as low as $149, according to a Reuters report. The news agency cites “sources with knowledge of the product” who say that the search giant is aiming to ship between 6-8 million units of the new tablet following a launch that could happen as early as July. Pricing for the device has not yet been decided, but Reuters has some interesting, if at this stage, speculative, projections. According to its insider sources, the tablet could be priced as low as $149 per unit — with the original Nexus 7 then discontinued — or it could retain the $199 price tag, in which case the cost of the original Nexus 7 would be reduced to encourage competition with Apple’s iPad range (which retails at upwards of $300) and Amazon’s Kindles (which start at $159).
