I believe it will be next year....and the plan was to add a team to make it 7 from each conference and eliminate the bye week for the #2 seed. So only the #1 seed will have a first week bye.
I have absolutely no problem with adding another team. We will likely have a sub 500 team win the NFC South this year, who will get in and have a home game. Adding a 10-6 team or even a 9-7 team to the mix that wouldn't have gotten in previously, only improves the quality of the competition. This will change from year to year, but you get the drift. It works both ways.
Making the playoffs is good for the Team, good for the fans, good for the NFL. In a league where home field is a huge advantage and a 1st round bye is still available there is an awful lot to play for during the regular season.
