Sony Xperia Tablet Z to be Revealed on 22 January

It appears that the rumoured Sony Xperia Tablet Z ( SO-03E/C690X ) will be announced by NTT DoCoMo in Japan next week on 22 January. The ‘DoCoMo Smartphone Lounge‘, which we assume is officially affiliated with NTT DoCoMo, has revealed that people will be able to see the Xperia Z & Xperia Tablet Z from Wednesday 23rd January to Sunday 27th January.
