I'd like to see a brand new live album or B-Ray/DVD, but I doubt they'll decide to release those ones. There's no gain in products like that anymore; the costs have been scaled to the stratosphere, and the prices of physical releases continue to rise. So same we can say about the studio albums, but with some brand new tracks and a promotional tour - that is an original reason to release new music. I think IM aren't about recording new stuff, maybe Senjutsu made them aware there's no potential to write some exciting music... I think they're focused on live shows, special tours 'til the end of their activity, and probably it's the best choice for now.
