I got this from the 2014 instructions- FAQs (DV 2014 registration starts tomorrow 2nd Oct). Some people might still be doubful about financial evidence for DV selectees. But here is the answer from the Horse's mouth!
IF I AM SUCCESSFUL IN OBTAINING A VISA THROUGH THE DV PROGRAM, WILL THE U.S. GOVERNMENT ASSIST WITH MY AIRFARE TO THE UNITED STATES, PROVIDE ASSISTANCE TO LOCATE HOUSING AND EMPLOYMENT, PROVIDE HEALTHCARE, OR PROVIDE ANY SUBSIDIES UNTIL I AM FULLY SETTLED?

No, applicants who obtain a DV are not provided any type of assistance such as airfare, housing assistance, or subsidies. If you are selected to apply for a DV, you will be required to provide evidence that you will not become a public charge in the United States before being issued a visa. This evidence may be in the form of a combination of your personal assets, an Affidavit of Support (Form I-134) from a relative or friend residing in the United States, and/or an offer of employment from an employer in the United States.
