Oh brother...
The next possible scene with Aiden is gonna be on Monday (ingame) PD16 I believe, and we're currently at around noon on Saturday (ingame) PD14. Depending on the task and time of day, the next task (5) could easily be 5-6 years away.
In other words; the next Aiden task might take place in 2030. The final task (how many are there in total again? 10? 12?) could be 40 years away. It's very questionable if you'll ever get to see the fifth task, let alone the final task. And that estimate doesn't even take into account the constant downward spiral aka slower development of the game.
AWAM will be long abandoned before L&P is getting to the last tasks unless he's gonna make some drastic changes to his development processes, which after 7 years of him constantly lying about "going faster" is as unlikely as winning the lottery 3 times in a row.
