Rumored once again for Samsung Mobile Unpacked event debut.
Samsung's Galaxy S4 is apparently scheduled for a debut on March 15, while a render and a new batch of rumored specs for the device have emerged.
SamMobile said a "trusted insider" claimed that March 15 is the date that the S4 will be unveiled. A European release will purportedly follow in early April. The unveiling itself is said to be taking place at a Samsung Mobile Unpacked event. Last year, the South Korean technology company announced the Galaxy S3 during an Unpacked event.
Invitations for the unveiling will apparently be sent out soon after the Mobile World Congress at the end of February. A new set of Galaxy S4 specs and a render, meanwhile, have also surfaced, as noted above.
Samsung, which has confirmed the existence of the Galaxy S4, previously said that the device will skip the aforementioned event. The smartphone itself was recently showcased in an alleged leaked press shot.

Oh...Apple is gonna HATE this beast...makes me smile just thinking about it.

nah I think 2 gb of ram is more than enough for a phone. Its not like your going to be playing hardcore games or something.
More cores does not help without threaded software to make actual use of them.
More RAM is a toughie since current 8Gbit chips are already stacked dies so jumping to 4GB would require twice as many RAM ICs until 8Gbit dies materialize.
Better battery is easier said than done in such constrained environments.
Personally, I would be more interested in reducing power than increasing battery size/capacity since phones and tablets tend to get uncomfortably warm around their SoC area when under prolonged load, which I personally find very annoying. If you could magically cram a 50Wh battery in a phone to feed a 10W SoC/APU, the phone would still be useless as a gaming/computing device since it would become unbearably hot when under non-trivial sustained load... unless you do not mind having to slap a HSF on your phone!
