They are just confusing their customers with such variants with similar names & features. Will put the customers in a dilemma when buying, in turn impacting their own sales.
They are just shooting themselves in their knees. They should keep their current product portfolio small & distinct IMO. They shd've stopped the prev version (or one before that atleast) when they released their RN7 series. Now, they add a confusion to buyers on whether to buy RN7, RN7Pro or RN7S coupled with more launch announcements. Most customers are impulsive buyers. He/she would end up postponing their purchase plans due to these factors.
So a surprise launch by Xiaomi Its gonna be 7S i thought it'll be Poco F2 . @Sparker0i why a new Model Launch ? They always Launch Normal,Note,Pro now why S
