Haven't read the paper yet but I thought someone had stated that Costco already operates in states that don't allow it, so not sure why it would be a requirement here?

Sounds like either way, Whole Foods would have to redesign if the law changes. Either design it for wine sales and have to change it if it doesn't pass or design it with no wine and change it if it does...seems more prudent to design for the law as it exists with the flexibility to change when/if the law changes (rearrange the aisles).
