Yes that's right folks, the Holy grail of PCB design is almost upon us. Altium are developing a free version called CircuitMaker
But before you wet yourself be advised that (at present) it is cloud storage only. Yes, no local storage. For many people (myself included) that's a deal breaker but to be fair Altium are listening to the great unwashed and this may change. I hope so.
If you have a week to spare you can read more about it here (40 pages and growing daily)
Note the vitriol about cloud storage. But as I said the features are still being decided so watch that space. At this point it seems that you can use the totally free version and "rent" upgrades, so for example if 100x100mm is the limit for the free version (I say "if") but you have a one-off requirement for a 100x200 you can rent that functionality for as long as required to do that job. Same for other features like say 6 layers etc.
IF the prices are reasonable I think this is a good model.
A free/cheap Altium has been the impossible dream for as long as I can remember, once you Eagle guys try it you'll never go back :)
