I really hope people won’t think that because this arbitrary limit was reached the version 6 is really coming “very soon”. I agree with Sprig (in the other thread) that the wording is a bit unclear and for uninitiated user who hasn’t followed the development it may give the false impression of 600 man hours for actually completing the v6 development. As far as hard realities go, I agree with bobc (also in the other thread). Wayne himself said in the mailing list that he expects the road to v6 to be more bumpy than the road from v4 to v5 was. To release v6 “very soon” they would need much more working hours. In the mailing list Orson said they try to outsource as much as possible. As much as that can be done, with enough money v6 could actually be “very soon”. Every donation gets us nearer, of course, and is needed. There are great enhancements planned for v7, too. There’s no end to good ideas. Every donation helps them to make those wishlist items reality even after v6.
Edit: Orson mentioned outsourcing in another thread here, not in the dev mailing list: When will Version 6 be Released?
Edit 2: I also didn’t remember correctly what Wayne said. Here it is: https://lists.launchpad.net/kicad-developers/msg36569.html
