October is a huge month for new releases. SE may think of releasing 2.4 to compete with those games.

HOWEVER:

A bunch of those games have been delayed to November. So SE may delay the patch to compete with the November releases. Either way, they could be screwed. If 2.4 is released in October, they'll probably lose people to the November games. If they release 2.4 in November, they lose people to the October games. OOOOOOR SE doesn't care about those releases and releases in October anyway.

In SE's mind, if people stop logging on to play the October/November releases, it doesn't matter as long as those people are still subbed and paying SE even if they aren't playing.
