I was just playing about with goggle and found the specs for this on a US web site
Samsung Galaxy S 2011 Edition specs - Phone Arena
Pretty similar to the original, Still single-core but at 1.4GHz processor, Android 2.3 out of the box. plus TouchWiz 3.0, as well as a bigger (1650mAh) battery. The other specs are the same - 4” Super AMOLED display, 5MP camera, GPS, Wi-Fi, FM radio and Bluetooth. Still no mention of a flash, but this was never a deal breaker (infact am yet to take my first "real" pic with it.
Having this sit in that upper mid range between ACE and S2 would make sense.
Much as a Love the idea of the power of the s2 its really just too big for me
