For the record, I'm sure if MK9 was patched or we got an "Ultra" version of it when Injustice hit, many people would have either played both Injustice and MK9, or dropped the former. Capcom actually updates their shit, which is why people play multiple games. NRS fans got sick and tired of the Kabal and Kenshi crisis, as well as "reset" exploiting characters, after 3 years. 3 years of tolerating that says a lot about the love MK9 received.
On the other hand, even if Injustice gets an update, it will still be horrifically overshadowed by MKX when it is released. That much I guarantee.
