Hmm for 10k+ sellers this season...

Definate
Steins;gate (Look @ the preorders!)
Nichijou (KyoAni is pretty much 100% to sell over 10k these days.. unless it's Munto related)

Confident

Hidan no Aria (Novels were slightly less popular than IS, airing in the same slot, good chance)
Gintama (Past history says it should)

Slight chance

Ao no Exorcist (Could it do a Full Metal Alchemist?)
Denpa Onna (I think this is either 20k+ or a big flop)
Hanasaku (Looks the goods.. but its not like True Tears sold well and that was excellent...)
Dog Days (No promo's released at all so far... I wonder what's up with this.. another swerve coming up perhaps..?)

Ignoring sales and talking strictly quality.. I think 2011 is going to be the best year for anime since 2006-2007... Spring 2007 is imo the best season ever for anime.. and Summer 2007 was hands down the best minor season.. and had no contender until Winter 2011 came along. You also see that the amount of anime shows are on the rise for Spring 2011 after becoming less and less in the last few years.

Good to see.
