"By having higher end hardware...we'll be able to do, for example, the real-time lighting calculations," Sega told Eurogamer last year. "That will give more presence to Sonic. We're not after realism. We're after making it more convincing."
6. Star Wars: Battlefront 3
EA has just landed the exclusive rights to future core Star Wars games, following the closure of LucasArts as an internal developer. This is a big deal.
We know that Star Wars: Battlefront 3 was killed part way into development. In fact, we've even laid our eyes on the game in action thanks to various pieces of footage surfacing on the net since its cancellation in 2008.
Given that we're also about to embark on a whole bunch of new Star Wars movies courtesy of the Disney buyout, an updated Battlefront game is exactly what we'd expect EA to be planning right now, with Battlefield developer DICE a strong bet to be taking the helm.
7. Fallout 4
Bethesda's post-apocalypse franchise has gained a new lease of life since its Fallout 3 revival, and there's every suggestion that a return to the wasteland is on the cards.
Bethesda Game Studios recently announced it was moving onto its "next major project" after Skyrim, and there was also a Twitter-based tease made by a Fallout 3 voice actor earlier this year. You do the math.
Given the epic scale of Bethesda's games, an E3 2014 reveal would be more likely than anything sooner. That said, a mere announcement at this year's Vegas gaming expo would still go down a treat.
8. Red Dead Rebellion
Ok, so it might not actually be called Red Dead Rebellion, but whatever title Rockstar gives the next episode in its western epic there's a good chance we'll see it on the new Xbox.
In a recent Asked & Answered session, Rockstar responded to a question about a possible sequel to Red Dead Redemption, stating that while there was nothing to announce, fans should "stay tuned for further announcements about the future of the Red Dead series". Is that a hint?
Red Dead Redemption was hugely impressive as far as open world game go, and a follow-up seems only logical. That said, if you're reading this, Rockstar, we'd be just as happy with a Bully sequel.
9. Half-Life 3
Half-Life 3 exists. We don't know what it looks like, how complete it is, or what it's going to be about - but somewhere in the darkest depths of the Valve dungeon, it's alive.
Now, there's a good chance that the game may have been postponed so as to make it a Steam Box exclusive when Valve finally releases its own console. After all, nothing could better promise to sell a platform like the most anticipated game of all time.
But even if that's the case, it's a sure bet that it will make its way onto the new Xbox at some stage. There's a running joke that because none of its games have had a full third installment, Valve can't count to 3. Well, it's 2013 guys. All signs are good.
According to the LinkedIn page of a certain Eidos Montreal developer, the new Thief game currently in development will be for "PS4/XBOX 720/PC".
Nothing's been confirmed by Square Enix beyond that, except that it will be coming to "other next-generation platforms" alongside the PS4 and PC.
Square-Enix says the new game will be a "reinvention" of the franchise, so those who've been in it since the early days might want to let the past remain in the past and prepare themselves for something totally new.
