How many heists on launch?

[Sweet Baby Jesus]

I see that the silver and gold editions of the game come with "season passes" that include 2 and/or 4 heists over the next 6 or 12 months respectively. So my question is how many different heists is the game actually going to release with? For $39.99 what is the initial release? Is the upgrade worth it? And for that matter, is the base game worth it at $39.99?

8 heists.
