From releasing a unified architecture browser including Linux support since 2001, Opera decided to put Linux development on indefinite hold, communicated through blog comments, and focus on Windows and Mac for their browser rewrite centered around the Blink engine that had its first beta release last spring. The promise to bring back the Linux version in due time was met with growing skepsis as the months went by, and clear answers have been avoided in the developer blog. The uncertainty has spawned user projects such as Otter browser in an attempt to recreate the Opera UI in a free application.
Tolfsen's statement seem to be in line with what users have suspected all along: Opera for Linux is not something for the near future."
