.....has any credible way of answering your question.
Until the release date is officially announced there will only be pure speculation. Only the folks in the Apple research & development know and maybe the highest level of corporate sales know anything..
I think it will have a fold-able 20 inch display, it will run Microsoft Windows, have a 13 core processor, run on a dilithium crystal battery with a 100 year life and no need for charging..
What features will it have?
