I have heard that debris removal has been happening daily [[night and day?), and a new roof and windows are on the way. Any firm word on where the building's future lays?

From Wikipedia:

The City of Detroit considered the building a "Priority Cultural Site" in 2006,the City Council on April 7, 2009 passed a resolution aimed at the demolition of the Depot.Seven days later, Detroit resident Stanley Christmas sued the city of Detroit to stop the demolition effort, citing the National Historic Preservation Act of 1966. The future of the building remains undetermined.

Then [[Wiki again, further down the page):

Renovation estimates have ranged from $80 to $300 million. The Detroit Wayne County Port Authority has the ability to issue bonds and could take part in financing.

The U.S. Department of Transportation has awarded $244 million in grants for high-speed rail upgrades between Chicago and Detroit. A consortium of investors including the Canadian Pacific Railway has proposed a new larger rail tunnel capable of handling large double stacked freight cars under the Detroit River which could open in 2015.With the new tunnel emerging near the Michigan Central Station, a redeveloped station could play a role as a trade inspection facility.

On May 5, 2011, the Detroit International Bridge Company announced it engaged the Ann Arbor firm of Quinn Evans to oversee restoration of the roof and windows of the structure. Bridge Company vice chairman Matthew Moroun stated, “We hope this is just the beginning of a renaissance for the depot."

On June 6, 2011, partial asbestos abatement on the first floor began. The work will be conducted by Professional Abatement Services, Inc. of Melvindale, Michigan.

As of June 28, 2012, work lights have illuminated the main lobby nightly. Abatement of debris continues daily. The website "talktothestation.com" has been launched by the Michigan Central Station Preservation Society to provide a sounding board for community questions and suggestions.

Is a lot of money being spent on the building, with no precise plan for its future?
