If rumors are to be believed, we might see the Ice Cream Sandwich launch on October 19 in Hong Kong just before the scheduled AsiaD event. This seems to be a believable rumor as Andy Rubin, SVP Mobile, Google (or Android Boss) and Dr. Won-Pyo Hong, Executive Vice President, Global Product Strategy, Samsung are already schedule to speak at the AsiaD and Google can certainly pull up some strings and make the ICS launch happen.
ICS and Galaxy Nexus announcement will most likely be schedule for October 19 morning in Hong Kong (around 1100hrs HKT – 0300hrsGMT – 0830hrs IST – 2300hrsEDT). Neither of this is confirmed, while the news is coming from source, the timing is all speculation.
If the event in confirmed to take place in Hong Kong, we will be hearing from Google in the next couple of days.
