OK - I got one of these "exclusive" items at AX and here's what I can say at this point (no pictures yet).
First, the pros. The toy is made entirely of plastic (no die-cast) and is of fairly decent quality. The toy is also fairly poseable and transforms with relative ease. It comes with removable landing gear, heatshield/canopy switchout and a display stand.
The cons. The lack of die-cast in itself is not a con, but its lack of structure/support makes for a difficult toy to display properly. The slightest nudge and the figure will bend in an unintentional way. This makes it very hard to pose symetrically. Its accessories are also small due to the scale, so some of the items (like the wing missiles, etc.) are somewhat useless in my opinion.
Paint application is fairly consistant and detailed adequately for the size/scale, but you need to apply the stickers to complete the "paint scheme" for the valk.
All in all, it's an OK buy for $25, but you get exactly what you pay for. These are similar in design to the Banpresto, but admittedly with far better quality.
Fast packs and other valkyrie variations are on the horizon and I hope one of the other boys on here can provide pics (Pat).
Hope this helps.
*EDIT - I see the Pat has already posted pics. Thanks, bro!
