You have to remember the 360 has had a head start because it was throttled to bring the price down. The use of a DVD drive in early models along with selectable HDD sizes sure helped but this means that people had to upgrade the console (eh?) by adding the HD DVD drive. This will also limit the size of games produced, because like the PC, the games will have to be written to bear in mind the specification of the majority owners
So now to bear in mind the coming of HDTV a new 360 model has had to be released adding features that previously had to be axed to cut initial production costs. this was never intended with PS3 but sadly has now occured due to the inability to bring the initial production costs down. Although Sony are sticking to their guns and keeping Blu-ray (How many DVD's did Oblivion neeed) along with the general hardware specs, sadly the biggest selling point, the ps2 compatibility, has been axed. Good for sales as the costs have reduced, bad for reputation!!! Now extra USB ports have to be added in order to play Rock band.
Lets face it though. Who's winning the format war? well, which console was sold out in the run up to christmas? And why? The innovative play style that has got the whole family playing together.
With 2 consoles and only one big TV in my household its not difficult to see which one will get played the most. The boys like the ps3 and guitar hero but when raving rabbids is mentioned the girls take over!!!
