The Constellation program has apparently been given at least a partial reprieve by President Obama. See the full story HERE in an article from spaceref.com.
Good news indeed that the administration has decided not to let US manned space program languish entirely in the hands of private business. Not that I don't believe that a number of private firms will eventually be up to the task, but for the time being they're still a largely unproven commodity. It really is best that NASA and the US government keep pushing forward with manned space flight for the time being, and give private enterprise time to prove their worth before we shift anything major over to them.
((And sorry about lack of updates lately, life has a habit of getting in the way of such things. Hopefully soon I'll be able to contribute a lot more than I have.))
