I can't see that they can delay.
Appics have already completed their ICO and are slated as the first SMT. They're currently on ERC-20 I believe, waiting to transfer across to SMTs once they launch.
The launch of the app is waiting on SMTs and surely they've had some sort of confirmation and assurance from Ned/Steem Inc that SMTs won't be delayed.
SMTs is slated for Q2/Early Q3.
Appics is slated for Q3/Early Q4.
Patience is all we need here.
Cheers!~
Let's just hope they are able to deliver on time :)
Appics have clearly stated they will use their other system that will be independent of SMT.
