Two new exterior designs will be under construction in the next 30 days, but a completely new prototype is a while off. The company has prepared a small building design, a square design and is looking at drive-throughs.

"[Drive-throughs] continue to be an opportunity for us as we move forward, but we have not done a tremendous amount of work in terms of really driving an initiative towards an entirely new prototype building," said Dave Near, COO. "That may be something that we look at towards the latter half of the year."

The strategic review process, announced in April 2007, has taken longer than expected due to the turmoil in the stock markets, the company said last week. That delay is slowing the conversion of company-owned units to franchises as potential franchisees seek certainty.
