Marvine: I wonder if really almost noone interested in the bundle anymore or if everybody (like me) is waiting for further price drops ;). At the time the first extra will be unlocked (if ever) the minimum price will be 0$. Strange.
I don't think the price drops are linear, or are they? My impression was that the amount of sales necessary to drop the price further increases after each drop.
That said, the sales strategy for the bundle is indeed a bit odd. For everyone who's _not_ interested in the bonus (or in keeping the price low), it's best to wait until the last minute with the purchase. This way, they don't create as much momentum right now as they could. This strategy does, however, keep the average price rather high, since the cheapskates like me aren't buying yet, so they don't drop the average.
It's an interesting strategy and I'm curious whether it'll work out. My guess is that you need a really good "beat the average" bonus section to make it work, and the one in this bundle might not be strong enough, especially considering that The Shivah has just been another bundle as well.
