Sony Ericsson historically hasn't had the best track record with timely Android updates. The Xperia X10 series launched with 1.6 Donut at a time when other devices were rolling out with 2.1 Eclair, and multi-touch was all but dismissed until eventually the company announced it found a way to incorporate pinch-to-zoom. Still, the entire 2010 Xperia lineup was eventually upgraded to 2.1, and more importantly, Sony Ericsson is a member of Google's so-called "18 month" groupthat promises support for its new Android devices for 18 months after each launches ("pending hardware support" and assuredly other important loopholes). So it's not really a question of if the 2011 lineup will get ICS, but more so, it's when.
