This is a little bit interesting, the model registered in January was the base 13" pro - that's a good 6 months later than the other models so maybe this wasn't originally planned to be updated at all (they skipped it altogether in 2018) but they wanted to completely ditch the butterfly keyboard and keep this model around.

Still three 'unknown' models floating about yet to be revealed. The rumour was they were all MacBooks, but maybe iMacs could be a possibility after all?
