This is according to Hugo Miller at Bloomberg who shed some light on the new date. However the 22nd of March date isn’t a stretch since earlier rumors have pointed to that date. However that doesn’t mean that nothing will take place on the 15th of March. While the phone might not be up for sale on the 15th, it is speculated that perhaps the device will be announced by AT&T and that pre-orders could begin on that day itself. Then again with the Samsung Galaxy S4 being announced on the 14th, perhaps a later announcement date for the Z10 might make sense, especially if they don’t want to be drowned out by the excitement. Either way check back with us on the 15th and 22nd of March for the details, if there are any to be had.
