I just updated the spring sales estimates on my site. All of this is based on the current trends on Amazon. Things can still change.
Love Live! has a rather big estimated event ticket drop(50%+), but it that should not stop it from becoming the top seller of Spring.
No stalker data for JoJo P3 yet, but I think we can assume it'll reach 15k+ at worst, and maybe even 25k if part 3 really is as popular in Japan, as they say.
Haikyuu!! has a good chance at 10k+, if it has the same storefront affect as KnB, 20k+/- for v1 and v2? and then it'll drop down a lot with v3? But who knows by how much? The estimated drop, just like Love Live is rather big(50%+). I mean sure, it has 2 volumes with event tickets, but it also has 9 volumes in total.
Mushishi S2 has a decent chance at getting 10k, if you include w2+ and a slight underestimation or it getting a small sales boost. It has no event ticket, so I don't think we'll see a big drop.
And that does for series that I think have a decent chance at reaching 10k or more.
Mahouka and Sidonia are doing good, but we are talking about a 6-8k~ average, nothing huge. But still good.
Gochuumon wa Usagi Desu ka? and Date A live II are also doing rather good, just as good as the previous 2. 4-6k~ average, maybe? I'm ofcourse hoping for a higher average for Gochiusa.
Ping Pong The Animation, Kenzen Robo Daimidaler, Mekaku City Actors, Isshuukan Friends, No Game No Life and Black bullet are doing decent(2k-4k~??). But these kind of sales are nothing special.
Kamigami no Asobi has a big estimated v2 drop of more than 85%, so make sure to remember that when v1 comes out.
Aside from(not on Amazon stalker yet),
Mahou Shoujo Taisen
Selector Infected WIXOSS
Kiniro no Corda Blue♪Sky
Baby steps
Soredemo Sekai wa Utsukushii
All of the series that I did not mention, excluding shorts, are performing horrible on Amazon.
