You guys might be surprised to hear from me after all this time, but I honestly believe the best chance of getting the sort of high elf models you guys want is if the faction barrier comes down somewhat and Blood Elves (and every other race) can group/guild with the Alliance/Horde, or even join it outright. If you throw in some blue eyes, it'll be no different from what the WC3R icons show, and you can always just make your own backstory. There's reason to change how the factions work based on the dwindling Alliance community for high level content, and it's becoming increasingly popular.
Side note: although the community manager restates what Ion says, you can't really expect him to release any other info through a ticket.
