Xiaomi Mi band 4

Update: 11/June/2019: Mi Band 4 is released in china today. Global version will be released soon.

Mi band 4 is going to be released very soon, in March 2019 or April.

"For Mi Band 4, it's going to be in this year. It will be in 2019. But I'm not sure, [if] it's going to be in March and April. But, it is going to be in this year. Each generation we learn something, we always do better. And [for] Mi Band 3 — you can take a look at 2018's volume, right. So it's really much better as compared to previous version. So we expect Mi Band 4 will have similar trend. So once we launch Mi Band 4, we expect that product will sell well. Right now, Mi Band 3 is still hot sale — is still [selling] really, really well. The margin is not shrinking, the shipments are not shrinking. So we will work with Xiaomi to pick the right time to launch Mi Band 4 in the year."
