Will there be Metal Gear Solid 4 substance

More than likely due to the fact number one was re-released on the Gamecube, and number two and three were re-released (substance & subsistance) offering new gameplay features. If you were considering buying the game I would hold out a while and get the ultimate version with all the usual bell and whistles which are thrown in when it comes out. I myself am holding out getting a ps3 and metal gear solid 4 until either they bring a slim ps3 out (Lets face it there gonna do one at some point) or they bring out a subsistance version of mgs4. I learnt from the last time, I bought mgs3 and a big bulky ps2 and 6 months later the slim ps2 came out and mgs3 subsistance came out!!! My fat ps2's lazer died shortly after though so I had no choice to upgrade! Hang in there and save your cash!!!
