Apple launched its iPad Mini in 2012 and back then the sales were encouraging, but now since Apple’s smartphones got bigger, having a 5.5-inch iPhone makes the 7.9-inch iPad Mini a rather less desired device.
So it seems that Apple is considering to give up on the iPad Mini, which could be discontinued soon. Also, it seems that Apple wants to sell more iPad Pro tablets which brings more money than the iPad Mini.
It also appears that Apple is looking to get rid of the stocks as soon as it can, as the iPad Mini received price cuts. Put all this together and we might think that Apple is really considering this possibility, but there no official confirmation yet, so we can’t say for sure, what the Cupertino heads have decided.
