How do you know when there will be a sheath?

Thanks isurus79

but the possibility to bloom without sheath is very low, isn't it?

Yes.

I should also ask, is the plant mature?

Sheath or no sheath it can possibly bloom once the PB's are healthy and it has not flowered prior. The shealth really is only to protect the developing buds from the elements and to support the stem that holds up the flowers. The buds actually emerge from an internal sheath within the larger one.
