Continuing Android software upgrades – Jelly Bean for 2012 Xperia™ smartphones

Sony announces which Xperia phones will get Jelly Bean

The cards are on the table - Sony just announced the update plan of its Xperia line. Here's the list of models that will get updated to Android 4.1 Jelly Bean and also the ones that will remain stuck with 4.0 Ice Cream Sandwich.
Sony's latest high-end Xperia phones - the Xperia T, TX and V - will be updated to 4.1 Jelly Bean in mid-Q1 next year.
Next up are the global versions of Xperia S, Xperia acro S, Xperia ion, Xperia P, Xperia go and Xperia J. The release date for the update will be announced later. It's still unclear what will happen to the localized versions.
And now, the ones left behind - the whole 2011 Xperia lineup (which got updated to ICS) will not be getting Jelly Bean because Sony "would not be able to guarantee owners of these smartphones the user experience you expect and we demand".
It's a bit disappointing that the Xperia J, which has a cut-down version of the Qualcomm chipset that powers the 2011 Xperias, is getting JB but the older models are not.
