At the turn of the year, rumours and renders appeared online of Apple's iPad Pro 2020 series. Slated for a March release, Apple appeared to have made only minor changes from the iPad Pro 11 and iPad Pro 12.9 that it released in 2020. While the information originated from reputable sources, it has now come to light that the next iPad Pro series may have been delayed until Q3 2020, instead.

It makes way more sense for them to wait and release just 1 stacked ipad in a world where the sales need to rise back to the hayday years of old. just my 2 cents sal.
Hm, if you go through the only publicly available source there is no mention of a delay. It just states that there might be a 5G device in the fall of 2020. You can think of many different scenarios where there'll still be a launch in march.
I think reports have been misinterpreted with this article. Other publications also haven't picked this up yet. Which means its probably unlikely - unreliable information.
