There are a number of proper replies to this issue throughout this topic. In fact one right above your reply. It is of course your choice to take the one, humorous, lighthearted post out of context in this entire topic and get all worked up over it.
We do have a date for the fully supported release of IPS4 now. I'm not going to tell you in case something happens but we are pretty sure we will make it. There will be an RC7 though as we wrap up bugs. I'm sure you will notice the bug tracker is getting more sparse lately. We also want to do an RC7 as we need to test our internal release procedure that will apply to the "real" releases. That is why RC7 will take a bit longer than the others as it has to go through more process controls.
I am curious as to why it matters? My understanding for RSS is that you get a certain number in the feed (5, 10, 20, whatever) and from there on the program you are using to monitor the feed keeps checking. So while you always have a limit in the feed you never actually miss anything because as new items are added it keeps track. I'm not sure how 10 vs 20 vs 1000 makes a different. Can you explain what you are trying to do?
You seem to be thinking backwards on this Everything in the Feature Plan came from discussions posted in our feedback areas and such. To then open a discussion about a discussion would create an infinite loop and crash the interwebs. Besides there's nothing stopping you from creating topics in our feedback forum as you like.
