Will I be able to get cheaper government insurance now that the Health Care bill has passed?

I have health insurance through my employer, but was reading that if you are within certain income guidelines, up to 400% over the poverty limit, you will receive a subsidy towards health insurance. So, I did the rough math, and the government option with the subsidy would be cheaper than what I pay for private insurance now. So, will I be able to decline my employer's health insurance, and instead take the lower cost option offered by the government?
