It is widely expected that the Sony PS4 would be on the receiving end of additional and more substantial updates in due time, considering how Sony Worldwide President Shuhei Yoshida’s confirmation that the features announced in February earlier this year have yet to make their way to the masses. Basically, the 1.72 and 4.60 firmware updates for the Sony PS4 and PS3, respectively, will bring along with them an improvement to software stability when certain features are used.
