It just makes sense if your product isn't selling great to keep the options down. Of course great for us and the XB1 is a good console but unless MS think this will shift the tide (it won't) and they can sustain 3 different models and whatever bundles they decide to have, they are going to have a lot of stock stuffing the channels. If they want to drop a new bundle they will have to clear some of that stock out of the channels which will lead to more fire sales.
All in all the slim will provide a boost in sales but after the honeymoon period, it will just drop back to the level of sales pre-slim. I don't think it will sell enough to have 3 different models, but opinions hey!
@bold. It can't fall back to the pre-slim levels because history tells us that MS and Sony revisions boost sales. It happened last gen. People like this new and improved versions of their favorite consoles, and the boost in performance will only increase support for MS while getting rid of the old stigma the X1 had on launch.
So it doesn't really make sense to assume that sales will just fall back to the original levels.
