Just this morning I was wondering to myself why Capcom hadn't worked out the details to bring Mega Man X4 from the original Sony PlayStation era to the PlayStation Store for play on the PlayStation 3 and PS Vita, and by amazing coincidence the company has announced today that it's bringing Mega Man X4 and Mega Man X5 to PSN in the weeks ahead in North America; X4 releases next week with X5 arriving the week after that.  Fantastic news!  I actually bought an old X4 disc some time ago along with Mega Man 8, but haven't quite made the time yet to replay either.  Maybe once I can load X4 on my Vita, I'll be able to find the time.  Being able to enjoy a few levels before going to sleep from the comfort of bed really changes how often a game is played.
