In case people haven't seen the news (and read this comment), Egnaro's cancellation was announced a couple of days ago (late August). Hopefully the final remaining chapters will be collected in tankoubon form - there's three more chapters, albeit still all from the flashback arc. If not, I'll try and get them translated at some point, as there's no way in hell it will get licensed now. I think it will, alas, remain as beautiful and incomprehensible as ever.
The Dengeki Daioh announcement is suitably vague, and Yamaji himself is also not giving anything away on Twitter about it. I think my favourite Twitter comment comes from someone saying "why was this running in Dengeki Daioh, it should have been in Harta or Aokishi", to which I say too damn right it should have been running with all the other series I apparently like with gorgeous artwork...
