Best Case Scenario: Niche pack ideas for $1.69 + tax. They fill the gaps between big releases, which is good because March-June is a long dry period. They don't take too many resources away from other packs, and go on sale from time to time.
Most Likely Scenario: Half-baked $5.00 + tax filler that takes time and resources away from other packs, and they'll be content meant for other packs, but taken out and sold separately.
Given how shallow most packs are, they're either going to be somewhat infrequent, or they take away time and effort going into other packs. As it is, the budget is shoestring and they likely don't have enough employees.
