We have plenty of beta testers available at this point, the hard part isn't finding people willing to play the game, it's finding people who we can trust not to leak the patch before we're finished testing, but even there we're fine asking IRL friends and family to do the testing.
What's slowing us down is that for various reasons most members of the team have either had to stop helping entirely for the time being, or cut back considerably. It's nothing acrimonious, and I'm sure most or all of them will be back by the time we start on Decode, but for the time being the only person able to make a major time commitment to the project is me. That means either delaying entirely until everyone can come back, or doing most of the remaining work by myself. I figure that as close to done as we are, I might as well keep at it, but where a team of five could probably finish the remaining work in a week or two, by myself it could be another month.
