The next Xbox and the PlayStation 4 will both be shown at E3 2012, reports UK trade publication MCV.

According to unnamed sources, Microsoft has "signalled to partners" that it plans to unveil its new console at E3 2012. Not to be left behind, sources say that Sony execs have told third-parties that it will not be left behind in the next generation and will also have its PlayStation 3 successor at E3 2012.

"Obviously we can't reveal our sources," wrote Online Editor Ben Parfitt on Twitter. "But you have my personal word on this - the source is exemplary, 100 per cent concrete, ultra high level."

It's not expected that Sony and Microsoft will detail price and launch details at E3, but the presence of three new platforms will be a first for the annual trade show.

Any kind of showing from Sony and Microsoft could put a real damper on the Wii U launch - details of which are expected at E3 - especially if Wii U is unable to compete with the graphics capabilities of higher-end consoles.
