Anyway, the phone will go on sale only in early April, so the Exynos processor with 8 cores, his 5 inches screen, his 2GB memory and the 13 MP camera will not be tested too soon, as many would desired. However, my advise to you is for contacting the local operators and ending preorders from now, to avoid waiting for months until the desired phone will be delivered to you.
Also Very expected is the new security software that will come tomorrow with Samsung, called Knox. This Smartphone will have all the specifications of the Samsung Galaxy S3, but improved. Anyway Samsung Galaxy S3 is great, but Samsung Galaxy S4 will be even better and it will overcome it.
Already on online sites you can buy Galaxy S3 at bargain prices, somewhere around $79.99, if you have just registered on the site. Sales are even greater for older members of these sites. Check the offers in the online environment.
