Since the last few chapters have only been about Kei and not the Gantz team, it'd be safer to say that we don't know if Izumi's gotten his new weapon or not. When he talks the other guy, Nishi they talk about the other Gantz teams in other countries. So either they've been doing a lot of research or know this from missions. Izumi says that the team is weak now too, probably because new members don't know what the heck they are doing. That's what I think.
