Samsung is to launch the Galaxy S4, the next version of its flagship smartphone, on March 14 in New York.
Samsung tweeted a link to a press invite for the event with the strapline "Ready 4 the show. Come and meet the new Galaxy".
The new handset is rumoured to be packing powerful hardware enhancements, including an eight-core Exynos processor and a separate eight-core graphics processing unit, according to ZDNet's sister site CNET.
Other rumoured features of the Galaxy S4 include a 4.99-inch SuperAMOLED display, 2GB of RAM and a 13-megapixel rear camera with 1080p video capability.
As well as the new flagship handset, Samsung also has its eyes on the enterprise market: on Monday at Mobile World Congress it unveiled a new security system it has developed in response to the BYOD trend, called Knox.
The launch event on 14 March will be the first time since 2010 that Samsung has launched its Galaxy smartphone in the US and comes as Apple overtook it as the top smartphone vendor worldwide.
Samsung has reported that Galaxy S3 reached 20 million sales within three months of launch, but sales have slowed in recent months. Worldwide, Galaxy S3 shipments declined from 18 million in Q3 2012 to 15.4 million by Q4 2012, overshadowed by iPhone 5 shipments of 27.4 million and iPhone 4S shipments of 17.4 million in the quarter, according to figures by Strategy Analytics.
Samsung's mobile division chief JK Shin told Korean news site EDaily the New York venue was selected after being swamped by demands from US carriers to unveil the device there, according to a Reuters report.
