I haven't seen any official renderings yet, but from the property owner's website there's this image that gives an idea of the overall massing, though I reckon it's more a placeholder rather than what the final design will look like.

As for the rest of the property, it sounds like they're planning for at least two residential buildings along with multiple new dining spaces across the site.
This is the Murray Journal article with the owner's plans for the site.

For the Best Buy/Barnes & Noble site it states that "Howland envisions building somewhere between 360 to 400 housing units, with a mix of micro, studio, one-, two- and three-bedroom dwellings." in a building with "five levels of living over a two-story concrete parking structure, and ground-level townhomes in front of the parking so it doesn't look like a parking garage.”
Also from the article - "Construction on one-of-three planned new restaurants will begin within the year, a collaboration between Bonefish Grill and Outback Steakhouse. The new structure will be 10,000 square feet of shared dining space, where customers can dine in and order from either restaurant’s menus.
After construction is complete, The Pointe @ 53rd will no longer be “one long shopping center” but will have two separate apartment buildings with traffic flow through the middle, including a pedestrian walkway accessing the retail, dining and courtyard areas.
Employees and residents will be required to park in the garage structure located behind the shopping center, which will boast 1,300 new stalls, leaving room for the restaurants and retail in front, facing west toward State Street."
So it sounds like there's plans for another residential building down the road, as well as more changes to the current parking lot.

I'm interested to see what they come up with and how it'll compare to what the city has chosen for the
downtown site as this site has potential to be more impactful and interesting. Both sites are around the same distance to Murray Central, but the Best Buy location will be denser and have a wider of shops nearby to support it.
