For anyone from EU who was interested, it seems the Vita releases of Space Hulk & XBlaze have been bumped back from July as was planned:

XBlaze is now 28th of August; Space Hulk is 25th of September
Still planning on getting XBlaze because I think the print run is going to be really low. Haven't seen any retailers stocking these.
