Hi Ferjim,
The NSK3480 is still being produce at the moment. As far as the new cases are concerned, I don't see the NSK3480 being upgraded anytime soon (within 3 months). We do have a new "Dark Fleet" cases (DF-30 and DF-85) releasing in April and we have also upgraded the LanBoy case to the LanBoy Air. If I get any information regarding the NSK3480 upgrade, I will definitely let you know about it.
Regards,
Antec
