I belive they are on roead map there are ongoing high value work like catapult IMO that is most challenging one which should take Nem on next lvl of performance.
But that one can take some time like year IMO, probably in backgroud guys are working on deals and when it will be done then we will know.
Personally i like that ninja lunches usually coins that are overhyped before price final cause mega DUMP on release stuff date.

I know that waiting is not fun but so far i don't have anything to blame devs they are delivering high quality job and not over hype project.
In long run if nem blockcahain maintain top possition in blockchain technology we will go on next level of price as whole crypto.

And very good for crypto is many different technologies evolving all the time all people will find space for them.
I wont give you date sorry from my view it can take even year or two before that major technology comes out.
