Come to thing of it last E3 360 was also running on Apple computers emulation or am I wrong?
But then again for some reason I feel like Sony is a bit rushing to get everything done on time. In one year from no hardware, no dev kits, no games, no finalized features, we have everything. And too much of them too. The HD, and the controller were unexpected, BR is a new untested disk format, we dont know what happens with the online service, Cell is a totally new acrhitecture etc.
On the other hand I am optimistic things will go smoothly. Didnt expect to see games looking so good in such a small period of time
