Upgrading from 34GK950F

[Tricyclthief]

Have the LG 34" and wanting to upgrade to something little bigger. I've read about the 38GL950G which is gsync model i believe and theres the 38GN950 which looks like gsync compatible. Anyone heard release dates yet for the GN? Are there any other 144-160hz monitors coming out soon that i should wait for instead?
