I wouldn't get it, same as others have said.
1) I can't always afford new games.
2) Because of 1 I may not get a game for a while after release, in some cases this causes problems. 2 Examples being,
a ) Over a decade ago now I played a game called Tombi (Tomba usa for some reason) as a demo, loved the fun of it, but the demo was out ages before release, when it was out I had forgotten about it in favour of more recent things, by the time I remembered it I simply could not find it anywhere and this is prior to PSN (which last I looked still hasn't added it) the game wasn't really mainstream or by a big developer (can't remember the maker now even) so I forgot again, years later I decided to look again, after some internet searches I eventually found out about the american name and a copy on ebay for £60 (more then any new game at the time) I didn't buy it way to much to play such an old game and the developers wouldn't benifit from it, if I had though why should I be punished for the lack of availablity to the game.
b ) A more recent example, I bought ME direct download on Xbox360 (19.99 which is more then I would have paid for a new or preowned physical version but thats something else) I played the opening and it didn't drag me in enough to stop me from playing something else I had, over a year later I decided to give it another go, after the sheer dissappointment of Skyrim I figured I'd go back to something old and I thoroughly enjoyed it, nearing the end I figured I might as well look for ME2 to keep playing the story before 3 is out, Couldn't find a new physical copy anywhere to order, the direct download version wasn't clear if it came with Cereberus for extra content so the price would exceed £30, and my other option was to get ME2 digital deluxe edition on Origin (which Im not fussed on I already have seem I don't need another resource hog on my poor PC) which my PC may not have run and I'd loss out on importing my character and the content differences it provides, this is also at £25 and didn't include all the dlc like LotSB and Arrival so that would be more on top, at least if it was steam the total may have come to less. Anyway after navigating the cost minefield and the lousy cerberus barrier I found a preowned edition from GAME at 4.99, yes I would have to pay about £14 for the network and more for the other DLC but was my best option and came to about £30 in total with alot of content. Obviously I was a late buyer here but I was still unhappy with the fact I was effectively punished for the games availability problems by Cerberus Network, if they next Xbox prevented that rather then simply provided an option like that which at least means some money is being provided to the developer (afaik) then I simply would not have bought the game nor would I be likely to buy the sequel new (which I've preordered now). Sorry the wall but it's worth pointing out the numberous issues that already exist, and even though I may not like things like CN it at least is an option not a requirement or a complete removal, if the 720 does that everyone ends up a loser MS for points Developer for continued profit and future profit of a late adopter of a series that then preorders the Sequel at full price and the players who lose accessability to games due to income needing to space releases or wanting to wait and see for reviews/simply would prefer other things. Someone mentioned "some lawsuit" would result in the removal I wouldn't be surpised if one of those lawsuit came from the developers that like to whine about it so much in the first place when they realise this.
