Why do people want Last Gen to die now? Cross-Gen Multiplats sell better its a fact

[Ruler]

I am really annoyed by the people who are calling out that older consoles have to die, mainly the cross gen games who are still in devolopement like Mortal Kombat X or Metal Gear Solid 5. But look at the sales numbers and you can see cross-gen games sell better than Next-gen only games

Taking the numbers from this site and choosing evolve and dying light as examples who are 8-Gen only multiplats right now. Both games pretty much floppped commercially.

I made a comparison below of new IPs who were released in Q3.2014-Q1.2015 and i am leaving out the PC versions from all these games as evolve was longer out for this system but dying light wasnt.

So i am looking at all of these new IPs first 2 weeks console sales and you allready can see that Evolve and Dying Light who chose next gen only had pretty poor sales even for next gen systems.

Neverless even with these poor sales you can clearly see that the Cross Gen games got an adionall boost from older consoles, some got over 50% what each evolve and dying light sold, some even outsold them like destiny has. Alien isolation sold also poorly but if you take 8 and 7th gen versions both together it still sold more than dying light in its first 2 weeks. 

Cross-Gen games

Destiny, new gen = 4008.959k  old gen = 1172.027k

Shadow of Mordor, new gen = 1034.908k old gen= 290.692k

Alien: Isolations, new gen= 336.521k old gen= 124.743k 

The Evil Within, new gen = 774.597k old gen = 340.423k

New Gen ONLY games

Dying Light = 544.017k

Evolve = 699.986k

and keep in mind i am only counting new IPs here recently released. I could also put watch dogs in there which had amazing sales or i could put call of duty, far cry 4 who arent new IPs but having all strong sales for last gen systems.

People who say last gen console versions have to die because it is sucking devoloping cost and making a loss are wrong. 

Imo its only not making sense for devolopers who arent good at porting to different platforms. Turtle rock for example wasnt good at devoloping last gen, do you remember they didnt release left4dead on the PS3 because of the more complicated architecture? 

So of course for studios who have expierence with only 1 last gen console its better to cancel last gen alltogether but as the numbers tell they are paying the price now.
