Milo was a tech demo and has always been presented as such plus it was Molyneux going crazy daydreaming as usual.... and the" power of the cloud" like people put it, is not something that needs to be proven it has been used and proved for over a decade now.... it's not like it is anything new in terms of technology.... it is just a question of how dev will use it for game enhancement that is in question here not the infrastructure and its theoretical capabilities.... those are already verified....
but yeah lets give you those 2....
Sony as always been famous for flooding press conferences with a load of marketing material to wow the crowds with stuff that is not gonna happen for a long while and sometimes not even look like what they showed in the first place....
not that I care it's 2 different marketing approach.... MS has always focused its announcement on the next 6 to 12 months material.... and Sony on everything they can throw at the fans at a T time.... one is frustrating (MS) one can be misleading (Sony).... I prefer MS approach cause it let us enjoy stuff one by one without hopping or waiting for stuff that far away on the schedule (i.e. the amazing mainframe power of the cell, gaikai, some game trailers in the past like GT or KZ (? can't remember) that are shown)
right now we still have many things to learn about XB1 and MS different material and objectives which makes things more exciting IMO.... TGS and Gamescom will be that more interesting for XB fans or gamers.... while Sony still has stuff to say I'm sure there is far less mystery therefore less surprises or anticipation to enjoy....
