+10 Oxidation state, Exist or Not Exist?

Chemical physicist and spectroscopist C. K. Jørgensen once said that one of the major goals of inorganic chemistry is to prepare compounds of elements in unusual oxidation states. In 2009, the range of oxidation states produced from chemical reaction was -4 to +8, and in 2010 Himmel's group showed that Ir compound with +9 oxidation state, [IrO 4 ] + , exists by electronic structure calculations. In 2014, Wang's group confirmed the existence of the Ir(IX) by matrix-isolation experiments. From these ideas, can it be stretched further? Let say oxidation state +10?

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2013 to Martin Karplus (Université de Strasbourg, France and Harvard University, Cambridge, MA, USA), Michael Levitt (Stanford University School of Medicine, Stanford, CA, USA), and Arieh Warshel (University of Southern California, Los Angeles, CA, USA) “for the development of multiscale models for complex chemical systems”
