Use of past tense when describing upcoming event

Solution 1:

It's not past tense at all, nor a mistake. "What we got" is an informal (very informal) idiom for "what we have."

She's saying, "I'm really excited for the market to open up to see what we have [on the market]."

You're not going to find it in real dictionaries, but here's an example from Urban Dictionary:

what we got next mate?
A simple Term uttered most commonly by a person in Secondary School who hasn't got a *** clue what the next class is.

Meaning, "What do we have next, mate?"

Solution 2:

Business is a game of timing right? Shutters are down for customers right now but people have built/are busy building behind the shutter. Holding that thought..

Since, our dear speaker is excited and would like to assume that there are good things ready and waiting to be launched once the market opens, she goes on to use "got" instead of "getting" or "will get".

Another way of justifying her usage of "got" could be that she might be taking a holistic view of the entire system. A system of which we are all a part. But because we work in specialised silos, often the left hand doesn't know about what or how much right hand has progressed. Still, both hands belong to the same system. Hence, the usage of "what we got" instead of "what we are getting". Where use of we the latter will be considering the consumers as a disconnected entity, not part of the system.
