I hope not. this is where the gaming industry has gone and, while it's done a few good things, it's done many things worse. the primary thing that ends up happening is, features that you should be expecting to see as built-in-when-sold suddenly become things you have to pay more to receive. also, companies feel OK with releasing not-ready product because they assume it will all be handled after the fact with patches (see Rage, Dead Island, Witcher 2, nearly half of the big titles released in the last year).
I don't think it will be as bad in the camera industry because the majority of it really still comes down to hardware and you can't easily upgrade that. I'd still prefer that when Canon releases a product, it's a product they are confident of and willing to stand behind. I'm pretty sure if they had technology like 4:2:2 or 16-bit RAW or crop mode ready to release, they would do so, but the fact that they have not yet means they clearly do not have the resources at the moment to dedicate to those tasks.
and, at the end of the day, it's also about letting people do the things they are best at. Canon is excellent as an OEM camera manufacturer. the aftermarket modding community (similar to the gaming world) also has some fantastic talent with a willingness to go the extra mile in some very focused efforts, and in doing so, can accomplish certain tasks better or faster than even Canon's engineers might. perhaps the solution, similar to what some companies have adopted in the gaming industry, is a pro-modder stance, where they make code and resources available to aftermarket modders that make it easier for them to root around in the guts of the system and come up with brilliant mods. there's very little downside/risk in this for Canon, as it's not like the majority of its user base runs around hoping to "unlock" their Rebel.
