There will also be a brand new promotional video for the game tomorrow, except it's debuting on Japanese television this time so I'm not sure when we'll get to see it properly. They're airing a rerun of Production I.G.'s Sengoku Basara anime this month and to sweeten the deal each episode will finish with a short clip for Sengoku Basara 4 Sumeragi. The screenshots shown at the link show a Sengoku Basara 4 Sumeragi Latest Information Corner (the traditional name for KobaP's news updates), and a Sneak Peek (Approximately) 10-second Theatre: Flame Shingen, Ice Kenshin.
That's all for this morning, though I'd like to draw attention to the Sengoku Basara Jubilee project on Tumblr as several artists and writers have started posting their contributions. If you've been wanting more fan fiction and art for the series, there are several great new works in there and it's helping me get in the mood for the series' tenth anniversary! Check it out.
