Before I begin, take this piece of information with grain of salt. This is the kind of thing that gets players all bothered for some reason. It would appear as though Microsoft weren’t given an advance copy of the Star Wars Battlefront trailer for their use because they had to use one that has Sony branding instead.
As you can see from the image below (pointed out by bravoIntel), the trailer that was posted at Major Nelson a.k.a. Larry Hryb has the Sony branding. But if you look at post now, it has been replaced. It could have been a mistake, but who knows. This is kind of expected since Sony and EA have a marketing partnership for Star Wars Battlefront but you would at least expect that Microsoft would get a trailer that has their branding and that too in advance.
On a far more interesting note, industry insider Shinobi602 has given some insight into just what to expect from the Walkers in the game. Apparently these vehicles are effectively on rails, and players simply man the weapons, most likely hinting towards a walker assault mode. The insider also spoke to a number of journalists who saw the gameplay footage and he was able to confirm that the level of graphical quality seen in the trailer are one and the same.
Shinobi 602 later added that we should, “Expect gameplay at E3”, which to be fair, is kind of expected. Shinobi602 is a reliable industry insider who gets his information directly from the developers and has been correct for the past many times. But one should always take insider information with a grain of salt as usual.
