That's a plausible theory if I ever read one. Home video market-wise I've only given my money to Lucas three (minus 1) times. VHS, 2004 DVD's (watched someone else's copy - returned them), 2006 DVD's. I haven't bought any prequel stuff as I know I'll get them in the 2007 box (not that it matters, but it's a bonus to campare to fan editions).
