This is already not true - if I interpret blockchain.info's statistics right, so far, we had four blocks with more than 1 MB (these need to include Segwit transactions), three of them mined today:

- block 481947 (1,032119 MB)
- block 482152 (1,00003 MB)
- block 482187 (1,00003 MB)
- block 482191 (1,00001 MB)

So things are moving slowly, but they are moving.
