The reason for the fast development cycle is presumably because Opera wanted to get their new version out in time for Microsofts browser ballot screen, which is being pushed out soon. The company is claiming that the new version is the "fastest browser ever". Benchmarks of the beta done by Opera and ZDNet supports this claim, and showed that even the beta was leading over other browsers in most cases. How the final version compares remains to be seen.
