The Razer Viper V4 Pro has already shown up in previous rumors, with what is thought to be a camouflaged version of the mouse showing up at a Valorant tournament. Now, the successor to the Viper V3 Pro has once again been confirmed, this time by Valorant pro, Canezerra, in a livestream (via BestGamers on X). Allegedly, the Viper V4 Pro is also being used by two other Valorant players. Prosettings.net also lists League of Legends pro, Myrwn, as using the Viper V4 Pro.

The current consensus is that the Viper V4 Pro will use the same or similar internals to the DeathAdder V4 Pro, but with the symmetrical shape of the Viper V3 Pro. This means it will likely feature the new dome receiver of the DeathAdder V4 Pro with a Nordic 54 series MCU, Gen-4 Razer Optical Mouse switches, a Razer Focus Pro 45K Gen 2 sensor, a slight decrease in weight, and minor physical changes, like a new coating and slight shape tweaks. The current-gen Razer Viper V3 Pro was released in April 2024, while the DeathAdder V4 Pro was launched in July 2025; by that logic, we can expect the Viper V4 Pro to launch sometime in Q2 2026 or shortly after.

Razer, the leading global lifestyle brand for gamers, today announced its modern take on a gaming legend: the Razer Boomslang 20th Anniversary Edition. Launched as the world's first gaming mouse, the Razer Boomslang did not just change the game - it defined a new era of play. Its distinctive snake-head silhouette became an icon of early gaming. Groundbreaking features such as 2,000 DPI mechanical ball tracking and on-the-fly sensitivity adjustment delivered precision unheard of at the time, setting a new benchmark when competitive PC gaming was still finding its footing.

20 YEARS IN THE MAKING. A LEGACY REBORN.
Two decades later, that promise lives on. The Boomslang returns in its 20th Anniversary Edition - reborn with cutting-edge technology for today's gaming era, while honoring the design and spirit that started it all. "When we designed the Razer Boomslang, we just wanted to get the unfair advantage in gaming, and that single spark helped ignite the entire multi-billion dollar gaming peripherals industry that we know today," said Min-Liang Tan, Co-Founder and CEO of Razer. "The Boomslang 20th Anniversary Edition is more than a mouse. It's a tribute to the community who made this possible and a reaffirmation of our motto that continues to guide everything we do: For Gamers. By Gamers."
