I would like to mention something about your industry dealers suggestions. For those who don't know, I ran the Dealer Room for many years (ie. 6) at NDK.
When Funimation, Tokyopop, etc come to cons, they sell things early, and usually cheaper. The sheer act of them doing this usually violates their own street dates (when a title is allowed to be put up for sale) as well as sells at wholesaler/distributor prices, undercutting *actual* dealers. While we love those booths and the people who run them and the companies they represent, this will usually encourage DVD/Manga dealers who carry more than one publisher of titles (or more accurately, dozens of distributors) to not come to a convention, because they lose a pretty fair amount of money, and they cannot compete with their own distributors...and nor should they.
Please note I have absolutely no control nor say in who is present in the Dealer Room and have not for about 4-5 years now (I now run Security).
One other piece of info...while asking for those dealers is great (please, keep the suggestions coming!) we can't always oblige simply because there are often no dealers in that category interested in coming to NDK. Trucking their stuff to NDK, setting it up, buying the booth, paying for power, phone, etc, staffing their booth for long hours with no breaks and then tearing it down and trucking it back is not always a profitable or desirable arrangement for some dealers. Many of the ones you see in the DR spend almost all of their time at cons, not in local stores. It's a pretty brutal life for those folks on the road. This has been particularly true for games dealers. You'll see one or two "add-on" dealers of imports/other games attached to bigger booths which have come and gone over the years, and this is often because it's hard to make money in such an industry. I sincerely hope a successful business in this can make it enough to attend NDK in the near future.
