Speaking at #animeblogger, DiGiKerot said that the ghosting is plainly visible on a PC, less so on a consumer TV (although is present there as well). Since you have to be a real videophile to see all of 625 lines, the ghosting basically becomes obvious during the fast movement only. Also, "it's a real shame about the video, because the rest of the release looks to be pretty much fabulous". Not an auspicious debut for NIS in U.S. market, but it could be worse.
UPDATE: He put up a whole post on the topic with large photographs and the screencap of the ghosting effect.
