Doubt it.
People said the same of Steam.
Took a few years for people to buy into it but they did. I'd be interested to see the statistics on PC games purchased via retail v. online.
Steam is a whole different thing than this gotta-stay-online-to-play-offline BS. It's an online store, not a copy protection per se. Though, I prefer boxed games over digital copies; I'd be willing to pay for good boxed material.
Although I don't normally use Steam, because their prices have a huge euro extra. I can get a boxed copy for 4/5th to 3/4th of the price on Steam. For example SH5 is 50 euros on Steam while the boxed version is 32 to 33 euros from online or 44 euros from a local store. The collector edition is a bit cheaper than the boxed version, but it doesn't have the box or other materials - just the overpriced digital stuff (including a strategy guide, which used to be referred as "manual" in the past, whereas the manual nowadays is more often totally useless than useful). I only used Steam during the christmas discounts when they had huge discounts that I really couldn't pass - nor would i really care what happens to couple of euros.
