I honestly don't believe there is a "launch" plan as it stands. I believe the situation is, as is, and however StarCitizen is sold today is exactly how they intend to push it going forward, a perpetual work in progress, and the press seem oblivious to it. Listening to Chris Roberts talk in these interviews, he often seems to use the language of start-ups and I'm sure he thinks he's "disrupting" the industry.
Even though I only worked in the "biz" for a short time, I got a sense of the mentality in the industry particularly in larger studios where any sense of making fun software is overshadowed by the important money men. There is no benefit to them changing the business model when they are taking in good money on "pledges", as long as it's legal it gives them a neat loophole away from having to support the product at an akward consumer technical level, it's neatly dodges inconvenient consumer review material and regulations/standards. It's no surprise to me that their current target of releasing S42 carries the "beta" prefix. I am sure there have been discussions around CIG about what the drawbacks are and I'm convinced they've concluded that as long as it's legal, the model they have now - with iterative releases and all new alpha/beta protection is always going to be their best option indefinitely. No meta-review for Star Citizen, No steam review, no magazine review, no age rating, no refund policy - Star Citizen doesn't need those things, those are for dirty consumers - Star Citizen just needs faith and cash and all the time to "get it right"
The most frustrating thing is that consumers, especially a small group of enthusiasts are over valuing the product and there is no regulation to protect them. I keep hearing the argument "it's my money I'll spend it how I like" and I'm sure those same arguments were applied to pyramid schemes until someone stepped in. I have nothing against the early access model per-se, but it needs a framework that ensures the consumer has visibility on this situation when they go in, currently with Star Citizen it's massively misleading for them to continuously claim that there is some eventual "release" that they can't identify a date for and leaving the consumer to take all the risk. If there was some mechanism for refund or someone was verifying the quality of pre-ordered virtual goods delivered on a reasonable deadline as described it might not be so bad.
