Wild pass is live. You'll have to buy a wild pass to play in wild format for any given season from here on out.
The cheapest way to buy it is 40 vouchers and you'll have to transfer your vouchers to in game.
Just before the end of last season I was pulling right around 2 SPS per win.
Here's my first win of the season

I pulled 1.775 SPS for the match which is a slight decrease in winnings relative to my last win from last season.

where I pulled 2.228 SPS. The drop is reasonable in consideration of the drop from Champion III to Diamond II, but does not cover the cost of my 88 cents to get into wild this season.
I'm still curious to see how this develops over the next several days, but if my SPS winnings don't increase then I expect to write off wild play and go back to modern for next season.
I'm curious to see if you've all noted similar disappointing results.
