Given the problem of getting 4.0.3 and Sony's reluctance to let it's customers know what's going on, getting a minor 0.0.1 update is as likely as seeing fairies at the bottom of the garden.
ICS 4.0.3 was released 16/12/11, we got it what a few weeks ago, some 5 months later. 4.0.4 was released 29/03/12. So Sony will release this update in August (but then again it may not)
I'd be more concerned about Android version 5, rumoured to be out later this year.
