Amazon is prepping for a massive invasion of their 7-inch Android tablets in Q3. Apparently, Amazon’s manufacturing partner Quanta (who also makes the Kindle and Playbook) expects to ship around 3 million of their dual-core tablets to the online retailer by October. This translates into roughly 800,000 to a million units every month for the remainder of Q3. This is actually a lot more than what Digitimes first reported with 700,000 to 800,000 units being shipped each month this quarter. As far as Amazon’s 10.1-inch quad-core tablet goes, the “Hollywood” isn’t expected until sometime next year and is currently being manufactured by Foxconn.
