Can we expect 2.3 this month or in April, since 2.2 dipped into March?
TL;DRNo release date is given for the next patch; the goal is a patch every month, slips are possible, and PTU length is hard to estimate.
To be determined, really. The goal is to try to get a patch out every month. We will sometimes slip, sometimes we won't, and we'll see how it shapes up. I imagine we'll know a lot more in about two or three weeks. I imagine we'll know a lot more in four weeks. Yes, we'll definitely have the answer in five weeks. Hopefully.
We've gotten the patch to PTU every month on schedule. It's always impossible to fully estimate how long a PTU period each patch will need, though. It depends on the available testers and the available resources to fix things.
There are two essential criticisms, one of which is totally invalid and the other of which is true. 'Star Citizen is a scam, we're stealing everyone's money,' blah, blah, blah. No, we're delivering something every month and you can see it. That's what really, really matters to us from a public perspective. We want to show you what we're doing. The second criticism is that this game has all sorts of delays and so on, and to that I would say it's Chris Roberts' game. It will never be quite on time, but we will always try.
