Google just held its Galaxy Nexus event in Hong Kong and we read just about every report and release in detail, only to find that Google didn't even mention Ice Cream Sandwich Android 4.0 for tablets, which is somewhat surprising.
At this time, there is no official information if and when Android 4.0 comes to tablets. Since Android 4.0 looks like the lovechild of Gingerbread and Honeycomb and gets a few new options, it's likely that we will see Android 4.0 on tablets, with a few tweaks of course.
Google just don't want to talk about it, at least not yet. Since Google chaps already said that Android 2.3 capable phones should be able to run Android 4.0 this definitely applies to any Android 3.x tablets since most of them have dual-core processors and quite powerful hardware to back it up.
We knew that the Samsung + Google event delay was not about paying respects to late Apple CEO Steve Jobs, as the phone won’t ship until November, and now announcing it closer to launch makes them look better. As for tablets, it’s likely that we should see some developments, like Xoom Android 4.0 and some other tablets this year, but we unfortunately don't have any updates or exact dates.
All popular tablets that run Android 3.x, most of them based on Tegra 2 and similar dual-core chips, will eventually get Android 4.0. The question is when. Google do you care to comment?
