As a fan of Macross/Robotech, I think I am mostly intrigued by the technology and the mixture of alien life forms etc. As a kid seeing that valkyrie in Robotech reminded me of my favorite F-14A Tomcat by Grumman. I'm not sure if it's pure accident or if Shoji Kawamori was heavily influenced by the Tomcat's design, but it was very thoughtful of Kawamori to show-off the Tomcat in Macross Zero.
And in the context of collecting valkyries to make money in the future, more power to those who can afford fifty-plus yamato valkryies. But the future is a gray void. I am not knocking anybody down, but take a look at the VF-1S Takatoku gift set (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=36568&item=5925848075&rd=1). Back in 1998, the piece sold for $1400 ... then came Toynami with the Masterpiece Collections ... and then came Yamato 1/48 scaled valkyries (bigger, better etc.)
Bandai will probably put out some Perfect Grade VF-1 GBP set...just as a guess, but who knows.
There are some collectors who play a big part in the consumer world, off-balancing other fans' opportunities in acquiring some figures. These are the collectors who buy numerous prints in hopes of reselling them for a profit. But what about peeps who can't afford to readily buy these valkyries ... they end up buying marked-up prices ... and are scolded for doing so ... it's not their fault.
If you really want to make money from these valkyries, go commission an artist or a company (G-System?) to create an all die-cast version ... and maybe, 100 hundred years from now, it'll be worth something in wallstreet-ebay.com? Hah. With "competition driving quality," your best bet is to modifying or make your own valkyrie.
So in the end, I'd say just stick to buying two of every valkyrie that comes out, LOL. One for the vault, and one to open....and don't hog the market by buying 40+ Low Viz valkryies!
By the way, the F-14 will be decommissioned soon and be replaced by the F-18. Also, if you guys get a chance, check out the program in KPBS about the Joint Strike Fighter selection...which pretty much is like Macross Plus (minus the love story)....Boeing's X-32 versus Lockheed Martin's X-35!
