It looks like the updated DualShock 4 controller, previously leaked, may be true- and that in addition, Sony may be planning an update to their PlayStation Move controller, too.
As discovered by Beyond3D forum member orangpelupa (via VideoGamer), applications for new PlayStation Move controller (CECH-ZCM1G) and a new DualShock 4 controller (CUH-ZCT2G) were filed with a certification agency in Indonesia, that appears to be the Indonesian equivalent of the FCC, earlier in August, presumably ahead of their reveal at the PlayStation Meeting early next month.
As far as the PlayStation Move goes, this even makes sense- the controller has remained the same since its introduction six years ago in 2010, and it even has the old PS3 branding, with PS3 buttons (the PS4 has Options and Share, not Start and Select like the Move controllers currently being sold do)- updating it definitely makes sense.
The DualShock 4 could definitely have done with an upgrade, too, but the upgrades for it seem to be far more incremental than I would personally want, so I can’t say I’m too happy about it. We’ll know for sure during the PlayStation Meeting in September, I gather.
