Psn/wiiware-VC/XBLA subscriptions ALA netflix/gamefly?

I buy about 5-6 games from these services COMBINED a year, but am interested in dozens.  Why do I buy/play so few?  I'm a cheap bastard and most of my retail games are through gamefly or sold when I'm done, can't due that with a download.
 
How much would you pay for an unlimited games/play per month for your console of choice?  Honestly I'd probably pay 40-50$ a month (I'd probably only subscribe 3-4 months a year when I have no retail games I'm psyched for) and that is MUCH more money than they get out of me currently.
 
It would be a logistical nightmare to figure out who gets how much of said fee's, but I think these first parties are insane for not doing this.

I don't think I would ever consider paying a monthly fee for XBLA, which happens to be the only of those services I use regularly. That might change if I had access to all three for one price or something, but we all know that Hell would have to hit absolute zero before they would even consider that.

I didn't mean all three first parties bundling together, sorry for the confusion but that would be an insane thought haha
