I don't know... Black Cherry sold [Oricon-wise] just over 1 million with a quadruple A-side that sold ~400k [all 4 songs were on the album], a double (ballad) A-side that sold ~300k and a huge ringtone hit that sold ~270k.
For Kingdom we have a single with 4 new songs that sold ~200k [only one song is on the album], plus other singles with sales around the 90-120k mark.
I'd have to be REALLY optimistic to see Kingdom as a million-seller.

Anyway, yeah, I think Ayumi's Asia Tour 2 announcement helped the stocks rise, too.
