[quote]Are you sure? Because all I can find about it is that 5 is the last one Link: http://m.ign.com/articles/2015/03/04/kojima-says-metal-gear-solid-v-the-phantom-pain-is-the-last-metal-gear-solid[/quote] Last Metal Gear "Solid". Not the last for the franchise itself. Remember there were two Metal Gear games before Metal Gear Solid. And then there's Metal Gear Rising. So another Metal Gear series may be developed. It's also the last one made from Kojima. Konami still has the rights to it.
