Do you mean the Original Farmers Market which is right next to the Grove?
The Grove is very much like Disney Springs. The Original Farmers Market is pretty neat, but WDW already has an area themed like it -- Sunset Ranch in DHS.
They could build a food hall there, which seem big these days. There's been a major one operating in Atlanta for a few years now (Krog Street Market) and several more are under construction. That may be what the Terminal is (I don't know) but that photo makes the Terminal look more like an indoor version of the Original Farmers Market with some restaurants but also a lot of shops selling products. Krog Street Market is almost entirely dining (there is a little bit of retail, but there's no butcher shop, seafood market, produce, etc.).
I don't know that all the other Disney Springs dining tenants (especially the QS places) would be very happy with a food hall going in and suddenly doubling their on-site competitors, though.
