Will get on the 10 scans in the morning. Forgot it wasn't TMMN with the 10 concepts, I found them on a tumblr post. So I will get some clear ones of them for you, Blaze.
@Gonzo: The previous tributes are still in of course, but 21 early pages are devoted to the new ones. Most of those tributes are 2 page spreads, of course, as you've seen with Ariga/Iwamoto/etc. The coloring of Shingo Adachi's Ryuusei pic seems off and Wily's skin in Ikehara's is grey, so some weird color choices. After some index pages, 30 goes back to the same Classic series pages in order, with 9 and 10's official art (12 new pages) after 8, but before RnF. There is nothing new for X, except for a few new IHX pieces for X, Dr. Light, Zero, Vile, and one Sigma. (What I scanned in my previous post, plus page 234)
The Rough Sketch section is totally unchanged. So, basically pages 30-270 have a mere 14 new pages.
The gallery section finally starts with some 'new' stuff. After the MvC page, there is a new page with just Zero's art from MvC3, Project X Zone's official art for X, Zero, Vile and Iris, and fatty Mcfat from SFxTekken. No concepts, nothing mindblowingly new to us. Next is the page that is my 4th sample, that includes the D-Arts Vile art and the bonus E-Can art. Then a page with tiny calendar art from the 2011+2012 Heroes/Villains/Girls calendars, and the idol Luna/Roll/Meiru art. After that, a page with CD art - We Are Rock-Men 1 and 2, 9 and 10 Arranged OSTs and...chiptuned Rockman??? Don't get that one, other than for filler. Then 3 full page images of the art for Kotobukiya's Rock/Blues/Roll kits. Half page for the infamous Roll Roll Roll Roll Roll pic.
The Comics pages keep the original stuff, but included covers for Ikehara's updated 7 manga, Izuki's 8 complete edition, Ariga's Rockman Maniax and Gigamixes, along with tiny pics for the bonus postcards he had. All books that came out after R20. The "Mega Man" section that included the Nintendo power poster and English box art now add DeJesus' retro bad box art for 9 and 10. The Dreamwave comics were actually edited down, so that only 6 covers are there, with no page samples anymore. And that's because instead, they added an extra 2.5 pages devoted to every Archie comic cover and variant from 1-21. After that, one page devoted to UDON Tribute, with just the two covers (Ariga and Chamba's) and Dickman's big pic scaled down to a quarter of the page. And then one full page image from Asiagraph 2011 - the one with Rock standing in the sewer water.
A few pages later, we get 8 pages worth of Cardass images. But when you cram 35 cards onto one page, you have to squint. And then there's a page devoted to all the 20th tribute art, which again disappoints as 30-some images are crammed onto it.
Character Archives are next, and where we find the new 9 and 10 concepts. 18 total new pages. I don't believe anything is new in the X sections, although they did redo and expand the Command Mission art to add an additional page. But only through enlarging and rearranging previous images.
The Special Section has 8 pages of artist interviews, with just three DASH 3 non-winning Aero images that might garner a tiny bit of interest. I think I'll scan that page, if anyone is feeling ambitious to translate, to see if it's even got anything meaningful. I don't know why, but then you have a two page XOver spread of official art (part already scanned) that is totally out of place, followed by 6 more pages of interviews to close it out. I do see one more mention of DASH in that interview, near official art of Barrett on his bike. And that closes it out.
So to say it was worth it? Probably not so much if you already have R20. How UDON would plan to break this one up, I don't know. I can't see the new stuff on it's own completely justifying a separate, smaller book, but I personally would have rather had it that way, then enlarging some pics to give it more volume.
