Game Industry Needs More and Better Ways to Make Money, Microsoft Says

Well, your idea falls apart on step 2 and it's math.
If they lower the sales only by $10 in order to achieve a 15% sales boost, they will be profiting less (discount of 16.6% versus 15% increase).
And if they drop it to $40, it's a 33% discount.

So, they would have to be sure that their sales will increase by more than 33%, which us hard to believe, even though video game industry operates as an elastic, "luxury" goods industry.

Also, I don't know your stance on Microtransactions, but you RP seem like an even worse rip-off, as they move beyond cosmetic into "gaming advantage" territory. It can also be considered gambling in many countries, leading to numerous legal disputes, thus putting players in certain geographic areas at a distinct disadvantage.

I think they need to continue what they're doing, DLCs, microtransactions, sponsorships etc. All those are purely optional, and better games get rewarded, bad games do not sell add-ons.
