It is clear what the new iPad mini 2 will be offering. A Retina display. What a new iPad 5 will bring to the table besides incremental upgrades is unclear.
Apple is supposed to release new iPad models as soon as April based on a report on iMore last week. I totally see that Apple can land a big winner with the release of the iPad mini 2 featuring a Retina display. I do not know though what an iPad 5 will bring to the table besides the typical incremental improvements. In my eyes it does not make sense for Apple to release a new iPad 5 for now.
If the new iPad releases are indeed next month we should hear soon more rumbles in the rumor mill.
