Xbox 360 and Xbox One fans have more than Halo 5 to look forward to ahead of E3 2014.

When Microsoft announced Halo 5: Guardians for Xbox One last week we assumed it had shot its pre-E3 load a little early, but it turns out the platform holder has more treats in store.

According to Xbox and Microsoft Studios boss Phil Spencer on Twitter, Microsoft intend to ladle out a few more tasty surprises in the lead up to the June show.

@bmuny101 There are a few things coming prior to E3. Show is getting set so easier to see what we want to talk about prior. — Phil Spencer (@XboxP3) May 18, 2014

Spencer said that showing off things like Halo 5 now will give Microsoft more time to focus on other stuff.

@AkkaksMichael Yea, wanted to make the show entertaining. Some special things I want to show so needed to do some things early. — Phil Spencer (@XboxP3) May 18, 2014

I can’t imagine what could be bigger and more important than Halo 5, but on the other hand, we know what we’re getting with Halo 5. Microsoft doesn’t need additional time to explain the concept. Whereas if it has something more avant-garde on the cards – well. That’s kind of exciting, right?

Goodness know what Microsoft will bring to the stage, but we do know it won’t be PC games – although Spencer did say to stay tuned on that front over the next few months as Games for Windows closes down.

@KillTheZombiess @TilSkywalker I'm very focused on PC right now. Probably not E3 but through summer you'll hear more. — Phil Spencer (@XboxP3) May 18, 2014

We’ll probably see some more Kinect experiences, though, despite Microsoft’s decision to unbundle the Xbox One and Kinect.

@Xone_br33 @lenrulesdaworld You will see new Kinect games and work from platform on Kinect. — Phil Spencer (@XboxP3) May 18, 2014

This year, we’ve been promised new IP as well as sequels, more games and less talk, and the best line-up Microsoft has delivered in years.

That said, not even Microsoft knows precisely what it’s bringing to E3 2014. You might be surprised to learn that companies generally don’t have their E3 line-ups sorted until pretty close to when the show starts, but it’s true.

@WiiYou The lineup at E3 looks good. A couple of things we are still trying to land but it's coming together. — Phil Spencer (@XboxP3) May 18, 2014

E3 2014 kicks off with Microsoft’s press briefing at 9:30AM PDT on June 9.

Thanks, Gematsu.
