All major points:Quote-NASA envisions the need for CCDev 3 or 4. Once round 2 is completed, and with Congressional approval it is possible to get started on a big commercial crew program -NASA has not made a final determination regarding the acquisition strategy for commercial crew beyond CCDev 2-NASA does not know yet if three crew flights a year is sufficient to meet International Space Station (ISS) requirements, or whether commercial companies can make a business case for it.-NASA is releasing a Request for Proposal (RFP) or an Announcement for Proposal (AFP) for commercial crew services in late summer 2011 and will be choosing 4-6 companies for the first round of efforts. RFP is for a contract and AFP is for Space Act Agreements. Edit: I dont understand from the wording if CCDEV 3/4 will be the " big commercial crew program" or if it is separate.

So stepping back out of the minutia for a minute and looking big picture context:Spacecraft: Dragon, CST-100, New Shepard, DreamChaser.I don't think CCDev3 will continue development of all 4. There just won't be the money if they want to field 2 maybe 3 end to end systems in time to take over from Soyuz in the 2014-2015 timeframe. LVs: Falcon 9 and Atlas V.Neither LV has any padflow / infrastructure to accommodate crewed launches. Not a critical path element right now but not inexpensive either.So I would say CCDev3 brings perhaps 2 of the 3 CVs including LVs on-line with CCDev4 for Demos / Infrastructure?

NASA says that it will possibly need 3 commercial crew launches per year. But I don't know if one NASA commercial crew launch per year for each company is enough to have a business case (assuming that there is 3 providers).{snip}

NASA hasn't decided if there will be a CCDev-4 but if there is, I imagine that it would probably be a continuity of CCDev-3 (both end to end systems programs).

LC-39's design is incredibly flexible if arranged properly. Make an MLP for each launcher to be used, roll it out when it's time to launch. Incredibly flexible design, due to this capacity. I figured out once that they could realistically store up to 7 MLP's, which means 7 possible launchers could be used.

The contract includes anoption for an additional Ares I mobile launcher. It is a firm fixed-price contract with a value of $263,735,000, if all options are exercised.
For a commercial company making a business case for 1 launch a year is easyJust set Price = Total_Cost + ProfitNow whether you can get NASA to pay that high a price is a different matter.
"And then maybe capsules are replaced as LEO crew taxi by SNC and BO. Or something".So replace a capsule such as Dragon that can make a pinpoint thruster landing on a helipad and could possible land on the moon with a glider that requires runways. Doesn't sound like progress to me.
Once again, I'm not allowed to have an opinion oh well....
"Furthermore, the integrated escape system returns with the spacecraft, allowing for easy reuse and radical reductions in the cost of space transport. Over time, the same escape thrusters will also provide the capability for Dragon to land almost anywhere on Earth or another planet with pinpoint accuracy, overcoming the limitation of a winged architecture that works only in Earth’s atmosphere."http://www.spacex.com/press.php?page=20110419Ok, I just backed it up. Not opinion but stated from Spacex's own website. Clearly it's not just my opinion but Spacex's as well.
Not offense, with that logic we have to discount just about every device that has not flown as incomplete and not worth our time that would include the up coming Mars rover and the Taurus 2 and Cygnus as well as others. You can't say that about Spacex and not include everything else that has not flown upcoming missions or technology.
