I'd be more concerned about Malkin's health and durability than parity in scoring. I recently acquired Malkin and I have worries too.
I wouldn't read too much into this. Bettman is a master spin doctor. If Crosby finished with 113, Tavares 106, followed by the rest of the pack and Benn at 87, Bettman would be praising the 100 pointers and saying how "exciting it is to see players putting up over 100 points." Bettman's "Never been better" statements have no shelf life - according to him, the NHL is always better today than it was yesterday and so forth. A % of it is spin.
The thing I have noticed most this season is that the NHL is no longer gifting PP's (and 5-on-3s) to teams like the Pens in large numbers. Perhaps this is just my perception, but in year's past, it seemed like the Pens and Caps were on 5-8 PP's per game! No wonder Crosby, Malkin and Ovechkin were scoring a million points. If the NHL is anything, they are inconsistent. Next year, I wouldn't be the least bit surprised if the Art Ross winner scored 105 (a 20.6% increase).
It all depends on the return. I think Malkin has the raw talent to win a scoring title any given year but he lacks the durability to do so. Because of this, his projections run the gamut from 70-110. Personally, I'd bank for 70 GP out of Malkin and expect 80-85 points (prorated to 98 over 82 GP). Anything above this for Malkin is gravy at this point IMO. I never expected him to score 130+ points. Never.
