It's mostly a marketing hype. Xiaomi is known for it's style for "releasing" a phone that's really cheap for the specs, but limiting the supply until when the price for the hardware drops. Hardcore fans who closely follow the company may get the phone early and brags to their friends about how good the phone is compared to the price thus driving up the hype, but when average consumer can actually get the device it'll not be so impressive anymore.
Now with this reputation more widely known then before, they may be trying to lessen the doubt by promising "weekly" update of the hardware. Thus when they finally have a big enough margin to supply at scale, people won't think the phone is "old".
