FYI: http://www.tsn.ca/nhl/story/?id=405739 is the PAs second (and most recent) proposal. Details of the first were never all that clear, but it seems the first three years were very similar (maybe identical), but the first had a 4th year at 57% instead of the two years described in that link.
The owners initial offer was well documented, their second was reportedly mostly the same, but changed the players share to 46%. Their last offer has few details, other than it was "simplified". Revenue split is also given in the link above. However, according to Bettman, that offer was taken off the table when the lockout started so the details don't really matter.
The PA has made two proposals. The 2nd was around ~2% less than the first. (Hard to say for sure, since the players are asking for a set $ amount rather than a set %. The % will depend on actual growth.)
The owners have made 3 proposals. The last around 5% higher than the first, though really it was the only one that was at least somewhat realistic. Also, it is supposed to be off the table now.
