The armor looks pretty good, although I'd rather like it without the damage reduction
But… I don't feel good about the preorder… last time I got something preordered, it was from the U. S. region one and completely incompatible with everything else (it was LittleBigPlanet 2 and man that's quite loss)
You should know, that if you pre-order a game from US, it will only work with a bonus content from US PS Store. Same thing about the bonus downloadable content included - you can use the code only on US PS Store. I was once suprised why can't I open bonus DLC levels in my Sonic Unleashed (from US of course)…
EDIT
You can pre-order from European store, they're supposed to have that DLC too.
