I'm now a happy member of N4-GAF.
Just bought one today.
I was really lucky to find one here in São Paulo, Brazil. I know it's hard to buy even in the USA, but here it's almost impossible. There are some sellers on Mercado Liv(b)re (Latin America eBay) that sell the phones without stock, so the people that try their luck usually pay the abusive prices (about 1000 dolars for the 16gig) and still have to wait days, even weeks to have the phones shipped.
To find one in a retailer here was damn good luck, still expensive, but a lot cheaper.
The thing is, it's being made here, it's already homologated (?) by brazilian FCC equivalent since december and nobody knows when they're gonna sell it. The 4.2.2 first image leaks were from a factory here, if you guys remeber.
So official price here is unknown, but probably gonna be expensive. The high end phones go for about 1999 reais (one thousand us dollars) unlocked without carrier. Carrier plans are expensive here and you only get decent quality for abusive prices.
tl;dr I'm happy
