James Olley of the Evening Standard relayed the news:

Wenger says his future will be finalised at a board meeting to be held after the FA Cup Final.5/19/2017, 8:26:47 AM
Wenger's contract expires at the end of this season, which Arsenal could finish with a trophy if they beat Chelsea at Wembley Stadium on May 27.
The Frenchman was otherwise coy when asked about his future, per Olley:
James Olley @JamesOlley
Q: Will this be your last game at the Emirates? Wenger: "Of the season, yes." Q: Ever? Wenger: "I can't tell you that."5/19/2017, 8:26:15 AM
Speculation has been rife for months over whether Wenger will stay on at the Emirates Stadium beyond the summer.
ESPN's Alex Shaw and Rory Smith of the New York Times are fed up with the situation:

Find the Wenger carry-on so tedious. Either say you're leaving or not. Rather self-indulgent at this point.5/19/2017, 8:28:16 AM

Put it this way: if it was Mourinho doing it, we'd all be banging on about what a massive attention-seeking egotist he is.5/16/2017, 9:30:18 PM
The uncertainty surrounding the club has been detrimental to the second half of their campaign, though it has been clear for some time Wenger will not be revealing his plans until the end of the season.
Arsenal's involvement in the FA Cup final naturally extends that even further.
Barring significant slip-ups from Manchester City at Watford or Liverpool at home to Middlesbrough on the final day of the Premier League season on Sunday, the Gunners look set to miss out on the top four for the first time in Wenger's 21-year tenure.
Arsenal's failure to sustain a title challenge over the past decade and repeated UEFA Champions League exits at the last-16 stage—which are frequently humiliating to boot—have increased calls for Wenger to step down from many Gunners fans.
It probably is the best decision for the club if the Frenchman moves on, and while Chelsea will be firm favourites in the FA Cup final, winning the trophy would be a good way to sign off on his incredible Arsenal career.
However, winning it could just as easily drive the 67-year-old to continue in the hopes of more silverware, and losing—or failing to get in the top four—equally could spur him on to stay in a bid to improve things.
It's difficult to know what will happen, but there is at least a more concrete time frame as to when his future will be revealed.
