Tomorrow (March 31, 2015) Xiaomi will announce a bunch of products. Some with the Xiaomi brand, some from other companies.
This is the final banner and the five codes for tomorrow:
NSSJ – CXB – DDS – TZC – AA
Same-day update: Some good sleuthing at GizmoChina. They believe the “TZC” isn’t code at all but part of the model number for a new Bluetooth-connected scale Xiaomi will introduce. If that’s the case, no one ever had a chance at decoding what Xiaomi claimed was a code. We’ll know tomorrow.
