I have seen the same reports and I think their overall fares will just go up to reflect the peak times you will be flying. Tues and Wed are usually good days to Travel, Weekends bad as far as fares since they are peak times, the 4 or 5 days before a holiday and after a holiday tend to be more expensive, I think it is just a word to the wise they are putting out there that fares will be going up even higher than they are now, I heard it mentioned all of summer is "peak" so you can not win.
One thing to remember with all the cutbacks most airlines are offering fewer flights so demand is up for the seats, ergo you are at the airlines mercy when it comes to what they charge.
To answer your question I do think you are safe if you already bought your tickets, I have mine already for November(bought the first day they were offered for sale) that being said I know our flights have gone up by over $100 round trip since I bought them in April.
