I'm super excited for this upcoming expansion. It sounds like its going to be the biggest one yet (probably by far), there are going to be a lot of new cards to fill in the gaps that GVG and Naxx will leave. Probably a whole new line of mech cards and everything. (Edit: just remembered gorilla bot, I think they have to release more mechs now)

PC Gamer: On the subject of cards like Loatheb and Antique Healbot, they serve important functions as tech tools to counter popular strategies. Will the spring set include cards which fulfill similar roles? Do you think that’s necessary?

BB: Sometimes yeah. There are a lot of anti-tech cards in those sets, and we know that those cards won’t be available in Standard, and when we release new sets we’re aware what tools players are going to want and need.

And

BB: Well Standard is going to grow and shrink over time because we’re going to launch that first new set—it’ll be a big set—...
