Have the devs said how Rifts will be purchased?

We know game time and paid at least i know that much.

Does this mean Shards & Cells? Will it be bought from the platform store? Is any information known yet?

I'm hoping they use those 2 and not a new currency. We could just used saved cells and shards we have.

I imagine the first one won't even happen until October sometime but it'd be nice the info/to have time to prepare for the first one.

If we learn about this closer to the release people will probably complain they didn't have time to grind shards/save up cells. (If it uses shards and cells)
