Sonys been around longer in the gaming world, so of course it has more fans than Microsoft at the moment, there was a time that there were more Sega fans than Sony fans but thats simply not the case now, (boooooooooooo to those who betrayed Sega), anyway, give it a few more years and more people will have grown up with a microsoft console next to their t.v. stand hence more microsoft fans.
By the way, i never left Sega
