Yes, no info, but pre release will start april 5th, That's mean they will add ALL cards in client 4th and reveal all cards 3d.
Almost sure in this weekend they will announce 1st reveal stream on monday or tuesday. Community reveals will start 2 weeks before as always, wednesday, i think. Oh, maybe, they will post about story things or about new mechanics in this weekend, but not sure about last.
I hope they will announce reveal schedule sometime this week around Wednesday at least..
With a few cards dropped between today and tomorrow.
Last expansion they employed a really brief period of showcase with duration of only 9 or 10 days before launch. If they adapted that format this time round we might be getting our schedule next Monday..
perhaps they're doing something different and revealing almost no cards so that we get to discover all of them on our own when the expansion hits. doesn't seem like a great idea to me though, really limits theorycrafting time.
