FWIW, launching a card product is complex and experiences many unforseen, unavoidable delays. Even if you have hundreds of millions of dollars in the bank, the wheels of big corporate bureaucracies seem to move painfully slow from the perspective of those used to moving at internet Bitcoin speed. There's so many different entities involved, each with critical paths and potential disruption points; at a bare minimum you have: BIN sponsor, issuer-processor, card network, card bureau (manufacturer), and program manager.

Plus, card networks have all these strange "blackout" periods throughout the year where nothing is allowed to get done. If you slip a milestone and some important component falls into one of those windows, your whole project timeline stretches out like salt water taffy on a hot summer day. Even once you have everything approved and locked-and-loaded, you can miss a manufacturing window and get delayed additional months, etc...

Having personally project managed a card product from beginning to end, I can sympathise with the lack of being able to provide a firm date.
