from early box breaks i've seen, the new 2010-11 Season Update has been yielding more hits than the 3 GU, 1 auto advertised. people have been getting 4 GUs, 1 auto, sometimes even 6 hits in a box that costs around US$65 on average. might be worthwhile. i'm getting mine in about a week's time, will update you all then.
having said that though, might be hard to get a nice "A lister" auto from there. i saw a Case break of 2010-11 Season Update on another forum, and the autos were mostly rookies or so-so team's players. or the auto could be from the added on prestige / R&S rookies cards that Panini introduced.
