Bleach: Heat the Soul 4's battle system

If you've never imported one of the Bleach fighting games you're missing out one of the best fighters on the PSP. Being a fan of both the anime and the game series, I was happy to see that more info has come out about Bleach: Heat the Soul 4 from the official site. Finally there will be playable Vizards. The battle system is upgraded and supposed to have a new component called 'Soul Blaze'. The creators say the game is based on the manga, not the anime which may explain some of the visual choices.
Lastly, here are the confirmed characters so far:

• Ichigo Kurosaki

• Shuhei Hisagi

• Ulquiorra

• Ikkaku Madarame

• Yumichika Ayasegawa

• Grimmjow Jaggerjack

• Hirako Shinji

• Hiyori Sarugaki

The game is due out 5/24 in Japan.
