Looks like some price cuts are coming - the PS3 as well as the XBox 360.
The PS3 will apparently drop to $500 and the XBox to $350. Meanwhile the Wii is the same price and hard to get.
I occasionally play a few games of Halo 2 against whoever happens to be online - after all Halo rankings were reset to 0 I have managed to climb back to a 7 and enjoy the 2 new maps. It helps to have a 40" screen and a nice surround system
I finally looked for and found some tips on melee and sword lunging (xbx, etc.) that give me a few more skills.
Network inequalities frustrate my desire for a perfectly level playing field at all times, but it seems to even out over time. The Bungie/MS folks at least seem to pay attention and try to make the experience better whenever they can.
