NHL competition committee are apparently considering several rules. One of them includes limiting goaltender equipment (specifically, they mention "equipment that serves the purpose of blocking over protection". Another one involves blocking shots. Both are not going to get passed quickly enough to be implemented in 2015-2016, but something to keep an eye on. I bet this has to do with creating more offense.
Personally, I kind of like the idea of creating more offense. Offense sells tickets. Fans want to see offense. Take a look at the NFL. Most profitable sport in the world (other than maybe soccer). They create rules to encourage offense. People whine about it, but hey, it's darn successful and it gives fans what they want: more exciting games. That said, I strongly disagree with anything that would outlaw blocking shots. That's stupid.
Will the NHL ever return the scoring days of the 1980's? No. The NHL would need to do some outrageous things to get scoring back to that level. We're never going to see that level of scoring again. Ever. However, I'm all for more offense as long as they don't put goalies or anyone else at a severe disadvantage.
