I found almost nothing concerning news cards to come with samsung 1.0ns chips except the zotac wc one, but having compared on my screen (have been reliable trying to guess the gap between two holes on reference pcb), I measured approximately 19.3/19.4 cm instead of 23 cm (reference) for the new giga GV-NX88T512HP card. pic

with new power supply design and smaller pcb it may be interesting. but I found no info about release date yet.
anyway, galaxy is releasing a new pcb design the 17th of this month so I guess the new giga card isn't going to reach the shops late.
