No. You really should read the RS news better and more often.
Botany Bay & BotWatch are NOT the nuke. They are simply a way of detecting and banning bots.
Optimus Bot Nuke has not been released yet. It was first to be launched near the end of September but Jagex's mistake that banned 40,000 accounts made them push it back and slow down. The Optimus Bot Nuke is supposed to be just like the first nuke, however it will not drastically affect game performance like the Clusterflutterer did and will supposedly break 98% of bots, just like last time.
Also, a thought I just had:
Jagex said before no more BXP weekends.... but they now are changing their minds. It starts on October 27th... just 2 days after October 25th, the 1 year anniversary of the first Bot Nuke, and 2 days after RSBuddy's countdown timer reaches 0. What if Jagex is planning to launch the Bot Nuke on Oct 25th, on the anniversary, AND the same week that they have a BXP planned. This means that they will be breaking 98% of bots immediately before the BXP weekend starts. Basically the only ones who will be partaking in this BXP then will be legit players, and users of color bots, OpenGL bots (most likely), and possibly DynaMac's reflection bot.
Overall it would be a very very well-timed and planned update. A Bot Nuke right before a BXP weekend would bring exactly the kind of publicity and reaction they would love. My theory is just a theory, however it is very probable, and it would make sense if it were true.
