Depending on how far the update has progressed by then, it's possible. And if I do announce a planned release date for the Beta 1 preview version in that update, I'll also reopen the development tester signup forms to give players another chance to get access to the future preview versions of updates, since I do reopen it from time to time, and since Beta 1's release will mark a major development step towards the game's completion, it makes sense to do that given the update's significance.
