There is still an issue with making new actions that include saving for web. While recording the action, save for web functions as it should. But once the action is played, regardless of the original format the saved image should be, it gives it an html filename extension. This can be extremely frustating when you have an action that saves over a hundred images from a single action.
I have seen posts in Adobe forums from many people regarding this very irritating bug, including posts from Adobe employees acknowledging the bug. This was present in the Beta, the initial release, and in this 13.0.1 update. No fix.

The employee acknowledged this bug THREE months ago (as of this post), yet all things considered, this doesn't seem like something that would take three months to fix!
I have spoken about this bug with a friend that is a computer programmer. Considering that the action is saving the file correctly, and it's only the name that is not saving properly indicates that this is a superficial error, and not an issue that would require rewriting the code completely. Also consider that this WAS functioning properly in CS5, and that this is a very easily reproducible bug. Adobe should have plenty of information required to correct the issue. I understand that this fix may be more or less difficult to do than what I am suggesting, but it should have been fixed by now.
I don't understand this mentality. Please Adobe... Put CS7 down for a little while, and fix what needs to be fixed in CS6. People (myself included) have paid A LOT of money for your products, it's not unreasonable to expect them to work properly. Bugs happen, it's understandable, but it's not unrealistic to expect a fix for them when the software is as expensive as it is. Is there actually any plan to correct this issue?
