My colleague wrote on the basis of leaked information in a previous articlethat 10 March is the debut date. The image turned out to be fake (it happens), Redmi India announced the release date on its official Twitter page.

So in 2 weeks and 1 day, on March 4, the series will be released, but in the meantime some information has been released ahead of the debut. The reason I don't use the word "leaked" is because this information published by Xiaomi. There is little concrete evidence, but it does reveal a few things:
The phone(s) will have a Snapdragon processor, which will be capable of gaming (question what kind of gaming :D), a new "stunning" design, a lighter and thinner design, a big battery (again, not very concrete) and fast charging. The new series will also feature higher quality sound and better haptic feedback. The front panel is protected by Gorilla Glass, of course it is not revealed which series or IP52 dust and water resistant.
What is not written on the pictures, but can be seen, is that like its predecessors, the back is curved, while the front is flat, with a camera hole in the middle above. And so that's it, obviously the manufacturer won't reveal much about a yet-to-be-announced series, but it will probably be a worthy successor to the well-populated Redmi Note 9 series, I hope they'll keep the prices down to earth.
