It seems surprisingly shocking that Rena Matsui plans to graduate.

That article that the TV report refers to the fact that Rena is going to appear on the 2015.06.10 episode of the Japanese radio show "All Night Nippon" (which, as of this post, will basically happen within the next 12 hours), and that Aki-P has stated that Rena is planning on making an announcement during the show. He does not specifically state what the announcement is about, so no one knows for sure what it will be. However the article (and thus the TV report) is making an assumption/guessing that they think that she's going to announce that she will graduate from SKE.
Now would this really be surprising if she did announce it? Not really. When one is a fan of idols, and specifically, when one is a fan of multi-member idol groups, this (members graduating/leaving the group) is something that one accepts and has to accept as something that will eventually happen at some point. It's a part of the deal.
SKE/Rena fans have been speculating for a couple of years now about her whether or not she had plans to graduate, and if she did, when she would announce it. That speculation obviously increased when she declared back in March that she wasn't going to participate in this year's Senbatsu General Election. She has also been getting more acting jobs during the last year or so as well. Along with the usual drama guest star appearances where she has in a minor/guest role for an episode or two in a drama series, this past year she had her lead/starring role in the movie
Gift, and she reprised her "Gekikara" character for a Majisuka Gakuen stage play/musical that ran in May. This gives the impression that she's pushing forward with wanting to pursue acting on a more full-time basis.
Now speaking as a Rena fan, would it suck if she announces her graduation from SKE? Hell yeah. However, as of this post, she has not yet made that announcement. We fans will just have to wait for her upcoming appearance on "All Night Nippon" and see/hear what she actually says during her announcement. Whatever it ends up being, we'll just have to deal with it.
