As of right now, the moderators on Big Fish are saying that the 6.99 Game Club price for a Deluxe game will be an introductory price for an indeterminate amount of time (thus, the implication being that at some point the cost of a Deluxe game will be more than 6.99 for Game Club members); this is why people are assuming that the price of a Deluxe game for a Game Club member will at some point in the future cost more than this.

Ok, I see. But I can still buy the game when it comes out at the $6.99 rate if I'm in the time period?

Yes, for the foreseeable future, the Deluxe game cost for Club members will be $6.99. We will no doubt get an announcement if and when the cost goes up.
