Exclusive FF7 remake would do it. It's also pretty much the only remotely plausible one (and still not very plausible at this point).
Alternately:
World of Starcraft or World of Warcraft 2 comes exclusively to PS3.
Sony buys Bungie.
Um... I really can't think of anything else that would match it. GTA5 wouldn't do it, because the next GTA is just going to be an incremental improvement over the last one. It's only the first entries of a generation that are truly revolutionary and generate all the hype.
