ASUS ROG Gladius IV Ace and Raikiri II Pro Launch in Japan October 30: 8K Specs and Battery Caveat

There is also an important qualification behind the controller’s headline battery figure: ASUS’s detailed specifications do not promise 79 hours with every feature enabled—or at its maximum polling rate.

Gladius IV Ace: lightweight, with room to add weight​

The Gladius IV Ace starts at 56g, with included 3g, 5g and 7g weights allowing adjustment up to 71g. ASUS describes a right-handed ergonomic shape informed by sports-science research. Its claims about reducing wrist strain remain manufacturer claims, rather than an independently established comfort result for every hand or grip.

The configuration count deserves clarification. While the Japanese announcement describes seven weight settings, ASUS’s earlier global announcement explicitly says seven additional configurations beyond the unweighted mouse. That wording distinguishes the seven weighted combinations from the 56g starting configuration. The weights are stackable, and ASUS describes the mouse as center-balanced.

This is not the mouse’s first public appearance: ASUS introduced it in its Gamescom announcement on August 25, 2026. October’s news establishes Japanese retail timing, rather than a first-ever reveal.

Sensor specifications and browser configuration​

ASUS lists the following capabilities:

• ROG AimPoint Pro 65K optical sensor, supporting up to 65,000 DPI.
• Maximum tracking speed of 800 IPS and acceleration of 70G.
• 11 selectable lift-off-distance levels.
• ROG SpeedNova 8K Gen II, supporting up to 8,000Hz polling over 2.4GHz wireless.
• Gear Link browser configuration, without downloading a dedicated configuration application.

For PC users who dislike installing another peripheral utility, browser-based customization is a useful feature. It should not, however, be interpreted as proof that every possible function is available without software: the launch announcement does not establish that broader claim.

Raikiri II Pro: replaceable sticks and physical controls​

The Raikiri II Pro uses hot-swappable TMR—tunnel magnetoresistance—joystick modules. ASUS also supplies interchangeable caps in different heights. Module replacement and cap replacement are distinct features: one changes the joystick assembly, while the other changes its contact surface. ASUS promotes low-drift operation, but that remains a durability claim, not an independently verified lifetime guarantee.

The controller adds two extra bumpers, four removable rear buttons and dual-mode triggers that switch between short-travel microswitch operation and full-travel TMR sensing. A full-color panel provides access to settings including profiles, button assignments and calibration. Its 8,000Hz maximum applies to wired and 2.4GHz connections on PC, not an unrestricted promise across every connection mode.

The battery-life fine print matters​

ASUS’s US product page provides this more useful breakdown:

These are ASUS’s figures, not independent measurements. The practical takeaway is straightforward: 79 hours is a reduced-feature, 1,000Hz operating figure, not the runtime to expect while using maximum polling with the display, vibration and lighting enabled.

What the announcement establishes​

The mouse’s adjustable mass and the controller’s replaceable joystick modules offer more tangible customization than a polling-rate number alone. But neither announcement establishes how much better an individual player will perform. Treat the specifications as capabilities to evaluate—not a shortcut to improved aim.

For readers outside Japan, the key boundary remains regional: October 30 is the confirmed Japanese launch date for both products. It does not establish matching US release timing or identical regional packages.
