T = ?89.2°C:
Dome A
Location: 80°22' S 77°22'E.
With a surface elevation of 4093 m, Dome Argus (Dome A) is the highest place in Antarctica, though one of the least-known places on the globe. It lies near one end of an elongate ridge (about 60 km long and 10 km wide). The ice thickness there is more than 3000 m, overlaying the subglacial Gamburtsev Mountains. Palaeo-scientists consider it suitable for collecting an ice core that will provide a record of past climate and atmospheric gas composition going back more than one million years.
The coldest place on Earth?
The worlds lowest temperature ever recorded was ?89.2°C in July 1983, at the Russian station Vostok, inland of Australias Casey station. Dome A is nearly 600 m higher in elevation than Vostok, so theres a good chance that the automatic weather station at Dome A will one day record the worlds lowest surface temperature. The coldest temperature reached to date was ?82.5°C in July 2005.

T = -93.2 °C:
Coldest place on Earth tucked in Antarctic ice pocket
14:07 10 December 2013 by Anil Ananthaswamy
Small dips in the snow atop the Antarctic plateau have set new records for the coldest ever surface temperature on Earth, a distinctly chilly -93.2 °C.
"This temperature is almost as far below the freezing point of water as boiling water is above [it]," said Ted Scambos of the National Snow and Ice Data Center at Boulder, Colorado, at a meeting yesterday of the American Geophysical Union in San Francisco.
Scambos and his colleagues analysed 32 years of thermal imaging data collected by NASA's MODIS and AVHRR satellite instruments and high-resolution images beamed back by Landsat 8.
The record was set on 10 August, 2010, when the surface temperature plummeted to -93.2 °C. Another pocket dropped to -93 °C on 31 July, 2013. These record lows occurred in small dips in the ice along a 1000-kilometre section of the ridge that stretches between Dome Fuji and Dome Argus, two of the summits on the East Antarctic ice sheet.

I was unaware that China now has a station (Kunlun Station) at Dome A - this video has a good representation of ground conditions:

Still, there is a solid chance to beat the 30-year-old record, believes Russian scientist, and
it could be done by Chinese scientists at Kunlun stationed opened in 2009.
It is uninhabited in winter time, but if they put a [automatic] meteorological station there they can register a temperatures lower than at Vostok station, Vyacheslav Martyanovtold RIA Novosti.
Kunlun station is situated in Antarcticas highest region known as Dome A (Dome Argus).
The station was opened on February 2, 2009, after the 25th Chinese Antarctic expedition made a 1,200km march from the sea-shore, getting to the continents hardest-to-reach area 4,093 meters above sea level.
