Along with the patch notes for Patch 29.0, we also got the Reward Track for Whizbang's Workshop to go live at the same time that the set does.
This time, the Track does have some differences though. One of the most significant ones is that there are less achievement, but achievements from Showdown in the Badlands will remain active and will still carry over as XP into this track. The Rewards track also comes with 2 New Coins.
 
Players will also get Li'Na, Shop Manager is their free Legendary on the Track, and you've still got time to theorycraft with her.
Quote From PlayHearthstone

Whizbang’s about to open the doors to his workshop, where a new Rewards Track awaits! When the Rewards Track refreshes with the Whizbang’s Workshop launch, all players will automatically be granted any unclaimed rewards on the current free Rewards Track and the Tavern Pass track (if purchased), before a completely new Whizbang’s Workshop Rewards Track takes its place.

Whizbang’s Workshop Rewards Track 

The free Rewards Track for Whizbang’s Workshop will include packs from Whizbang’s Workshop, a random Epic card, two random Legendary cards, Tavern Tickets, a new card back, and lots of Gold! There are also 14 Golden cards along with the Li’Na Shop Manager Legendary card from the set!*
