When Sony Ericsson released the Xperia Play earlier this year, it said that the long delays seen with rolling out Android updates seen with the X10 were a thing of the past and that it would ensure new models carried the most current version. It appears to be sticking with that resolution, with the soon-to-be-launched Xperia neo shipping with Android 2.3.3.
The Xperia Neo is being released on Telstra from July 26, available on a 24-month contract for $59 a month. (Telstra has a 3-month local exclusive, something we've known since way back in February.)
It's one of the first phones to take advantage of Telstra's HD voice option, which offers better quality audio. I'm testing one out at the moment, and will offer some more detailed thoughts on the phone later this week.
