I'll be interested to see the design/sizing etc but will I rush out and buy on.....probably not - or at least Nintendo are going to have to make it easier to transfer DSiWare before I'll be too interested.

Anyone who claims they can see these differences while playing (and/or that they make a difference to the enjoyment level) is either a liar or an android!! I have both systems and in some cases the same game for both (I game on PS3 but kids prefer 360 ) and have run comparisons and I would struggle to tell which was which so all the time that went into this feature is laughable. I also agree with an earlier poster in that the real "proof" is to look at the exclusives so in March compare Forza 3 to GT 5 for example!
