After the events of the X-Men storyline "Schism" conclude and Uncanny X-Men ends with issue #544 on September, a (predictable) reboot will ensue and we will see the birth of two new X-Men comic series come October - namely Wolverine and the X-Men #1 and Uncanny X-Men #1!
Obviously, the split after schism is very real, with Wolverine will be leading his own team of merry mutants (with the new book taking its name after the 2008 animated series "Wolverine and the X-Men"), while Scott Summers/ Cyclops builds his own group in the relaunched "Uncanny X-Men" series. It's not known who's going to who's roster thus far, but the poster above seems to hint (or mislead) us at who will be at Wolverine's team or Cyclops' team. Safe bet is by the time Schism ends, we'll know what the full rosters of both will be.
