Hello wyytamtravel
Welcome to the SBB Community.
We are a customer support forum run by volunteers.
Certainly; they will soon be available for sales.
However, no Swiss resident would ever want purchasing tickets that far in advance.
Keep in mind that these tickets are not cancellable; should there be a change of plans (unable to travel), you will throw away money.
Furthermore, Supersaver tickets are fine for travel from A to B while you are sure to be able to meet the depature time. However, they do kill any flexibility are therefore not recommended for sightseeing trips where you might want to return a bit earlier or later depending on the weather and personal preference. A Saver Day Pass or a normal Point-to-Point ticket could be handy in this situation.
Kind regards,
Roland
