Sony need to resolve some crucial issues:
1. Latest OS/support updates
2. Near-future-proof hardware to match the future software updates, and
3. Consistent developer support to all its older phones.
When most phone makers have dual-core androids, they got stuck with single core(till xperia arc, by when galaxy s2,droid razr, etc were going great guns). In fact, the absence of a dual core processor on a top-end phone like this was one of the negative points of this beautiful and feature-rich phone(both xperia arc and xperia arc s)! But Sony need to anticipate the future android releases and estimate the hardware requirements for them, and implement those elements in their phones so that
they can update the version easily without any problem/undue delay.
