I played MGS1 despite never having played MG and MG2. I imagine MGS4 will come with a 'previously in the series' thing to read like MGS1 and 2 did, and the story will have enough flashbacks and explanations to make the storyline clear enough for new comers anyway.
However, the MGO Beta recieved quite a bit of flak from people who were expecting it to play like COD4, so I'll be surprised if the same thing doesn't happen with MGS4 too.
