SMIC is another example of decreasing transparency in the industry, nobody knew about their 7nm process and progress until someone messed up with a chip made by them. At the end of the day is very probably that they would make the process public but there is the case that they could also keep it a secret only offering to a few selected clients.
The sames goes for SMEE they could announced the dual wafer stage machines upgrades, their immersion tool, the new packaging tool. or they could not, they are private companies and they only respond to their owners and the goverment. There is another research project that SMEE is developing that very little people knows about and they already have some patents on it.
