How long should this take?

Partially rebranded Future Shop/Best Buy store, Granville and Robson Street, Vancouver, BC

On May 28, 2015, all of the Future Shop locations in Canada were closed. The owner, Best Buy, announced that some of the locations would re-open under the Best Buy banner.

Why has this not happened? Apart from the staff uniforms, what else has changed? The sign outside this store still says Future Shop.

If Best Buy can't be bothered changing the branding of the stores, why did the firm both to trash the Future Shop name? Has the store changed, or was this merely a way for Best Buy to cut its advertising costs in half? How much longer will this changeover take?
