I have to agree with rcsplinters.
First of all, Washington has never operated on a multi-year budget. Congress changes it at their whim, or by necessity year to year. If circumstances or technology makes significant changes before the 2012 or 2013 budgets are approved, I wouldn't expect these long term funding projections to hold. Even then, Congress can, and often has, amended funding bills. If Obama's initiatives have taught us anything, it should be that should there be a change in Administration or Congress, all of these plans are nothing but powerpoint presentations, and multi-billion dollar programs can be cancelled with no appeal.
What we also ALL need to realize is that immediately starting Super-Heavy Lift does not compete with Commercial. It is for a specialty launch capability, that simply is not profitable for them to pursue.
Some of you will argue the emphasis on SHLV competes for Commercial Crew funding, but if you look at the timeline it will take to develop Commercial Crew (2-3 years, minimum) and man-rate their rockets, the Senate Bill pretty much follows that expectation that there will not be anything available until 2013. It also makes provision for review and possible allocation of funds should they beat that timeline. One member of the committe actually said that they intend to match the Obama Plan funding, just not bringing it into play until the Commercial Crew companies have something to show.
The "multi-purpose crew vehicle" (aka the new Orion) does not compete either. It also is for an entirely different purpose, BEO missions. Again, this is not an area where commercial can make a profit, as they will be few and far between. Alternatively, if needed, it could be launched to LEO by Atlas V Heavy, Delta IV Heavy, or Falcon 9 Heavy provided they are man-rated. This capability could actually benefit Commercial launchers, and is inherent to them providing Crewed Services for NASA anyway, so is a necessary step.
What these initiatives DO give us, is a redundant, back-up human space flight capability until if and when Commercial Crew comes on line.
