Xbox 720 announcement in April?

[UPDATE] Following the publication of this story, The Verge also reports that Microsoft will hold a press event in April to announce the Xbox 720.

The original story follows below

Unspecified developers and "industry professionals" have informed CVG that Microsoft will announce the Xbox 720 at a one-off event in April. This is later than the rumored March event and would notably take place after the 2013 Game Developers Conference.

In addition, a "senior Sony official" who asked to remain anonymous told the site that the PlayStation 4 unveiling this week "at first caught Microsoft off-guard." This person added that, "We definitely ruffled some feathers."

Microsoft spokesperson Larry Hryb--aka Major Nelson--took a shot at the PS4 event this week. Writing on Twitter, he said "Well then. This meeting is running a little longer than expected," followed by "Announce a console without actually showing a console? That's one approach."

The PS4 is officially due out this holiday season. Microsoft's Xbox 720 is also believed to launch during this window, though Microsoft has yet to comment on the rumored console.
