I don't think Wessal needs to see fins. I would imagine Wessal has a lot more first hand knowledge of what will be reported in the fins and has been able to validate SLJB/LFWK activities well before it was announced publicly Wessal could begin buying 25% of SLJB in the open market. IMO, Wessal wouldn't have "bought" into that situation without some solid DD.
I pretty much agree with everything else you said. So many variables at this point. All anyone can do is wait and see.
