I found out an answer, I am not sayin that this is THE answer, but here it is..I downloaded the Leaflet 0.8-dev from http://leafletjs.com/download.html and added this into the construction of the map.
var somePlace = new L.LatLng(32.7150, -117.1625);
var mapOptions = {
center: somePlace,
zoom: 8,
crs: L.CRS.EPSG4326,
attributionControl: true, //define the source else where..
};
MAP = L.map('map', mapOptions);
var esriLayer = new L.TileLayer('URL TO THE EPSG4326 BASED TILED MAP SERV/mapserver/tile/{z}/{y}/{x}.png')
map.addLayer(esriLayer);
It works for my webmap service and tiling scheme.. so far..I hope this helps someone...
