It's not really good comparisons, and power like everything else only make up part of the package.
If you compare XO to 1X then everyone expects the XO to outsell the 1X due to the casual market.
If you compare 4pro to 1X then other factors come into play like mindshare, market share, game library, perception, etc
In other words I wouldn't expect it to answer that question any time soon
Guess if 1X ends up really successful it may show that power helped? If it doesn't do as well, then how do we judge that?
If X1 was speced similarly to 4pro and same price, does anyone think it would outsell it or do better than what X1 will do now?
