Ann: Trading Halt, page-100

Yep agreed

Technically a trading halt can only be for a max of 2 days and you can't have consecutive trading halts except in connection with accelerated capital raisings

If 4DS can't provide the required announcement in relation to the trading halt by Wednesday they should request a voluntary suspension.

If they don't make that request and the matter is not resolved to the satisfaction of the ASX then the ASX will put them into involuntary suspension at the expiration of the trading halt period

I reckon they'll still be compiling and assessing and reviewing come Wednesday so a suspension from trading will be on the cards

But that's purely my speculation
