Samsung has announced that it has broken the 1m sales barrier for the Galaxy S II in South Korea, smashing sales records in the process. Meanwhile, mobile comms chief J.K. Shin has confirmed that a sequel to the GSII, aka the “Galaxy S III”, is planned for the first half of 2012, while a Samsung Galaxy Tab 4G slate should arrive later in the year.

Details on the two new devices are unknown, with Shin only saying that the tablet would be built upon, and improve, what the current Galaxy Tab models offer. The 4G standard it will support is also unclear, so it could be LTE, WiMAX, HSPA+ or – most likely – all three to suit the various carriers.

Samsung actually sold 1.3m GSII units in May, Shin says; the original Galaxy S took 70 days to reach the 1m mark. As for the ongoing legal battle between Samsung and Apple, Shin dismisses it as not being “legally problematic.”  ”We didn’t copy Apple’s design” the exec insisted, “we have used many similar designs over the past years.”
