Sony Sirius or Xperia Z2 isn't the only flagship Xperia device going to be launched for 2014. Sony will also announce Xperia Z2 Ultra and Xperia Tablet Z2 aka Castor during the official announcement of Sirius.

According to a tweet from @gadgetleaks, Sony Xperia Z2 will be accompanied by two new devices based on two predecessors, Xperia Z2 Ultra and Xperia Tablet Z2 Castor.

However, Sony Sirius doesn't have an exact location yet, and rumours about Mobile World Congress attendance has been confirmed by Sony which means the tweet didn't specifically reveal where all three will be appearing this year.

A few weeks earlier, Sony set an event in Jakarta, Indonesia on March 5. Local media received invites with a tagline "Life is an incredible journey. Discover how with us on 5 March 2014," showing people jumping into the sea. This event isn't also confirmed as well and may only present the regional version of Xperia Z1 Compact.
