Now we can confirm that the Heist league will continue in poe 3.13. In the latest patch notes, we can see that GGG has simplified the Heist league mechanism. Although, the whole process will stay the same you will see that all rogue levelling will be faster.
Kurai, as well as your first Rogue's Markers, can now be found starting in Act 6.
Smuggler's Caches now always drop a Quest Contract if possible, in addition to an ordinary Contract.
Smuggler's Caches now appear less frequently, and Contracts, Blueprints and Rogue's Markers now drop less frequently.
Kurai's second and third quest contracts now spawn more monsters during the escape.
The number of Rogue's Markers you get from completing contracts above level 68 has been increased. You'll now get (on average) 20% more markers from Level 83 contracts.
Job Experience granted to Heist participants has been increased across the board to fit the lower frequency at which players will engage in them.
Vinderi's chance for items from Heist chests to be doubled has been reduced at all levels. It is now 14% at job level 5 (from 20%).
Huck now grants increased experience to players in Heists, up to 20% at job level 3.
Poe 3.13 will be released tomorrow. In the new league, we need to create new characters. This requires players to have a lot of poe currency. However, players have no more time to prepare, so we need to buy poe currency online.
