This is upgrade is nothing more than being future proof. It does nothing to current iPad owners and its simple.
No developer will be making games for the graphics power of iPad 4, everyone will make sure their games are low spec enough to run probably even on the iPad 2.
Even if developers will make use out of the iPad's 4 graphical power, their games will only be released about 6-7 months into the future, making it closer to the release of the iPad 5 and 7 months of almost useless graphical upgrade.
Think of new consoles, all the good games start coming within a year after release, and looking back at it, the first games released are usually the worst in graphics(compare release titles for PS2 vs latest release for the system)
