Classic changes - basic class cards

Will basic cards unlocked by level-up change? I'm asking,because I would like to know if I should rush leveling DH to 60 before next rotation. What's estimated date of next rotation?

Quote From Blizzard in Core set announcement

With the Classic Set joining the Legacy Set in Wild, all Classic cards and their Golden versions will now be craftable and disenchantable. Basic cards and their Golden versions will be granted to all players that have Wild unlocked for free at rotation, as will the normal versions of Demon Hunter Initiate cards (Golden Demon Hunter Initiate cards will still be craftable and disenchantable).

So it sounds like there's no need to rush to 60 for Basic cards, since we'll be given all the golden ones we're lacking anyway.

As for Core set cards:

Quote From Blizzard in Core set announcement

Like the Basic Set, you’ll earn Core Set cards by leveling up each class. All Core Set class cards are rewarded between levels 1-10 for each class, and Neutral Core Set cards will unlock based the sum of all your class levels combined, up to the combined level of 60. Golden versions of Core Set cards can be unlocked by completing Achievements associated with winning games as each class.

So again there's no need to rush to 60 with DH, since only a combined level of 60 matters. Golden versions will be earned via achievements, not class levels.

Finally, I don't think we know much about when the next rotations happens. It sounded like the Barrens set will be out whenever it is ready, which could be anywhere from mid March to late April for all I know.

Yup, you'll get get Core Set cards through leveling up. Level 1-10 of a class will give you class specific cards, while all other levels after that will give you neutrals.

Pre-purchase offers end March 22. To my knowledge, that has never been incorrect as an indicator of the launch date. It's pretty much always the very next day, or at least later that week.

Pre-purchase has always ended on the same day as the release, BUT these are not normal times and the deeper we get into the pandemic the more each set's development can be affected. I suspect the 22nd of March is when they want to release it, but as Iksar said in a Q&A, if they need to push it back into April they will.
