Samsung’s (005930) Galaxy Note phablet lineup is about to see some serious new competition… from Samsung. According to a report from SamMobile, which has a good track record when reporting details about unannounced Samsung products, the South Korean vendor is developing two new supersized smartphones that will launch later this year. Unlike its current phablets, however, these new handsets will fall under Samsung’s popular Galaxy brand and therefore may not include some of the Notes’ more appealing features, such as S Pen stylus support. The Galaxy Mega 5.8 is rumored to feature a 5.8-inch display and it will reportedly launch in late May or early June. Then, the Galaxy Mega 6.3 will seemingly follow in mid to late June with a comically large 6.3-inch touchscreen.
