An Open Letter from Indie Royale outlines plans to change the way their sales of indie game bundles will operate (thanks nin). For reasons mostly related to logistics and server load, they no longer plan on adhering to a strict schedule of a new bundle every two weeks, and they will begin accepting preorders, which will require flying blind. Here's a bit:

• We'll be removing a strict schedule of one Indie Royale bundle every two weeks. You can still sign up or follow us to find out when the bundle goes live. And we won't be changing our general concept and list of upcoming bundles. But we're continuing to target the near-term for the next Really Big Bundle, which will now launch next week after the U.S. Thanksgiving holiday.
• We now realize (and our smouldering servers agree!) that there are a lot of people who are waiting when the next Indie Royale bundle launches. In many cases, you may be reloading patiently to buy it almost no matter what, since it's such good value for money. So we're now opening pre-orders for the next Indie Royale bundle, at a recommended contribution of USD $5 but a minimum price of USD $3.99 (current and future Indie Royale bundles will launch at an initial live minimum of $2.99.)
• Why do pre-orders? We know that you're all busy people, and you may actually not be on the Internet (?!) the second it launches. So it's a simple way to guarantee you get the Bundle, albeit sight unseen. This means that you won't know what games are in the bundle until it launches. But you are guaranteed to get the bundle at a low minimum price, and you will be supporting hand-picked, high quality independent games along the way.
