I get what you are saying but Devs push this hardware beyond what they are capable of. Look at Xbox's UI? It is fucking slow because the hardware isn't strong enough. The menu system in NHL11 and 12 were slow as shit because of memory. Both of these are based on my limited knowledge and a bit of a stab at the dark but the programmers seem to be pushing these things harder than they are meant for. These consoles are designed for today, not tomorrow. That;s all well in good but the 360 has currently 7 years under its belt. The specs of the thing today are a joke.
