Based on a conversation started at the FUNimation forums and then confirmed here via retailer Right Stuf as being accurate in its lists as supplied from FUNimation, it appears that the Sengoku Basara release is doing something a bit unusual. The show is set for release in October on both DVD and Blu-ray for the first season and it appears that the Blu-ray release has four extra bonus mini episodes that the DVD release will not have:
While you see this more with Hollywood releases when it comes to extras, it's not that often we see it with anime. FUNimation recently indicated that their Blu-ray releases are seeing better penetration on some titles with fans in comparison to DVDs (and the number of fans going Blu-ray only is growing by the feedback provided) so it's not too surprising that we're seeing more Blu-ray releases. But it is surprising to see OVA content like this as an exclusive as it potentially alienates fans, though it does lead to an interesting conversation as has been evidenced about people not being able to afford a Blu-ray player. While this argument certainly had merit a couple of years ago when they were around $400 each, the fact you can get good players for under $100 these days - which is 60% of the retail cost of this set alone! - it's harder to make that case overall, though there will always be some fans who simply can't for some reason.
If you were planning to buy the DVD version, does this change your plans, and if so in what way?
