yeah I don't see it as beneficial to the consumer. While steam is great with its online sales, not all companies are going to be so generous with its price cuts. Thus, there is a good chance that we will get very few sales, and even less price drops. Based on my experience on the PSN store prices are usually pretty fixed for example: the price of fallout 3 (game of the year edition) has decreased in price; however, all the dlc content on psn store remains as expensive the day it was released (last time I checked).
Speaking of PSN, in light of what happened to Sony I think Microsoft and Sony will try and get out of this online store business. I couldn't imagine maintaining said store generates much revenue compared to the costs of operating it and the risk/responsibility in maintaining customer privacy. I think the risks in having peoples information lost and suffering repercussions will cause the console companies to move away from maintaining a store in order to protect themselves.
This idea of digital download exclusivity idea, will also hurt those who buy used games, your going to alienate part of the gaming demographic. I know some will say that its not necessarily a bad thing because the developer doesn't get the money from used sales. But let me ask those who buy games new: Do you sell your games once you've beaten them? Do you use said profit to purchase more new releases? For all the damage it does perpetuate a cycle that allows new games to be purchased (because if the used market disappeared so to would some gamers due to price etc.).
There is also the issue of bandwidth, in Canada this is a huge issue as it is with other places as well. Some people don't have extensive bandwidth to download a lot of games.
Finally, this will only further complicate the whole argument between owning and leasing contents and programs between customers and publishers.
There is also the fact that people enjoy going out to the game shop/electronic store and browsing the selection, socializing with other gamers etc. This whole idea that gamers want to shop in their underwear at 2:30am doesn't accurately reflect me or my gaming friends. I prefer going outside and interact with merchants and such.
No I think Nerf Ninja is right, digital distribution of content only benefits the developers and publishes at the cost of the consumer, don't be fooled by their claims otherwise; the wolf never tells the sheep his intentions.
