Well its imported by Samsung India, so its not in dealer's hand if Samsung are importing it. Also, I think I will stick with I9100G for a while. Better sound quality (OMAP has better audio DAC than Exonys), no yellowish screen, more RAM, no color banding, less heating, better battery life outweigh the cons like few less benchmarks and lack of ROMs. As long as it gets ICS, I see no harm. I mean the same chipset is used in Galaxy Nexus, Moto Razr, Nexus S, Optimus 3D use the same chipset, albeit the Galaxy Nexus has 84 Mhz more core clock in GPU and others having 100 Mhz lesser clock.
(I9100G has 300 Mhz core GPU clock, others have 200 Mhz and Galaxy Nexus has 384 Mhz)
Also, the ROMs to play with CPU clocks and rooting are already released. One just released yesterday.
