According to a new report by KGI, Apple will soon introduce a stylus accessory for its iPad products, targeted at the expected (but still officially unconfirmed) larger-screened ~12 inch iPad Pro. Both products are quoted for release sometime this year, with KGI most recently quoting a Q2 launch window. The stylus would apparently charge using a Lightning cable.
Although KGI reports tend to be based off of supply-chain sources, which have proven very reliable in the past, Ming-Chi Kuo does not allude to any such indicators for the stylus prediction report. Instead, he highlights a number of patent filings in recent years by Apple on tablet styli and a need to differentiate the upcoming more premium iPad aside from screen size.
