I've come to the conclusion that MacGruber 2 is the new Anchorman 2.  It's the sequel we'll want for years and years, but the studio will keep waiting to see if the cult fanbase is big enough to warrant a greenlight (or if there's an empty spot in their calendar).  It's also worth noting that Anchorman: The Legend of Ron Burgundy made waaaaaay more money than MacGruber.  But Will Forte can look forward to being asked about MacGruber 2 every time he does an interview, and he still seems fairly optimistic about the possibility.  In April, he said "there will be some form" of the sequel, and now he tells Rolling Stone, "June 10th my writing partners John Solomon, Jorma Taccone, and I are locking ourselves in a room and writing it."  Forte also told Rolling Stone there have been discussions about bringing back Kristen Wiig and Ryan Phillippe.  Of course, last June, Forte said he would be writing the script in the next six months, so he could just be messing with us.

Even if we hold out hope for a MacGruber 2, we shouldn't expect it for years unless Forte rockets to the A-list.  If he receives enough critical acclaim and attention for his performance in Alexander Payne's new drama, Nebraska, that might not be out of the realm of possibility.  In the meantime, just keep chanting "KFBR392".
