would this be a good idea?

if they make today's games downloadable, it should be cheaper.  If not, I wouldn't care for it.

Sony already does it with a few games, and I think Microsoft could benefit from it, as long as they still make retail.

 I 100% agree

Yeah, I like the dual-distribution concept. I haven't bought any retail titles via the PSN Store, but I like to know that I can if want to.

Well I think it's a good idea, but full games on the psn are as expensive as on blu ray! They should be at least 10-15€ cheaper (50€ for a new game is a good price IMO).

Really?  Like I said, I've never took advantage of the option yet, but in my mind I thought they were cheaper at first glance. 

I think they should be at least $15.00 cheaper, because they are saving $5.00 on distribution/freight costs and alomst $10.00 on not having to use an expensive Blu-ray disc.

The only reason the are the same now is b/c Gamestop and crew would mark up to save face--everyone would at least try 1 dl game for the heck of it and many would like it enough to stay w/ that format.
