I've read on reddit about possible Shelley delay

Just saw a post on reddit talking about how the shelley release is allready looking at a delay from
q1 to q2/3 2019. can anyone confirm ?

I believe im Cardano but from a trading point of view im worrying about how this fallout will effect the price. Im a long term holder but any delays will only lead to market share being lost.

There were no official announcements on this. Shelley is expected somewhere in Q1 2019.
