For those not familiar with lupinko, he's a guy that teases leaks about Capcom's fighting games all the time over twitter and has, as far as I know, never lead people the wrong way. Two of his tweets read like this:
Strider Hiryu
"All I know is dat s*** will be goin' clockw0rk, hype b****** cuz he be comin' for ya neo"
* A reference to Clockw0rk, a notable player of MvC3 who played against another player Neo in a money match. Clockw0rk played Strider/Doom/Sentinel
* Lupinko said we got 2 obvious clues, this is the first.
Phoenix Wright
(GameFAQs won't let this text go through, but just imagine some Japanese text and then a Kirby ASCII thing that looks like pointing (`_`)>
* Roughly translates to: Phoenix Wright's name in Japanese followed by HYPE and what looks like a little dude pointing.
* Lupinko said we got 2 obvious clues, this is the second.
