I really really want MS to blow me away tomorrow. And not just because they are due or because Sony underwhelmed with a focus on trailers. I really hope to see whats possible next gen. I want to see photorealism sure, but I also want to see interactivity we havent seen before. I want to see Far Cry 2 fire physics x100. I want to see fully living breathing cities like cyberpunk but on steroids. I want truly emergent gameplay where a small skirmish could take you from one end of the map to the other like GTA3 did back on PS2. Only on a larger scale.
Above all, I want to see what I dont expect to see. Destruction, massive NPC counts, photorealistic graphics like hellblade 2 are all good, but my imagination simply cant match the imagination of talented artists and directors who have been doing this their entire lives. I hope this new piece of tech allows them to push boundries and blow minds like they could never do before.
