I don't really see what you mean by "DLC" crazy though. It's not really that bad.
SF4 comes out on consoles in 2009, year later, SSF4 comes out, adds a ton of new stuff to more than warrant buying the game, and at a fraction of the price of the original. Year later we get AE which is available DLC or a Disc based add-on.
Same thing with BlazBlue, we got CT, then CS, then CS2, except CS2 is a free DLC patch, but if you want the new characters (Makoto, Valk, Trinity), you gotta pay up for them.
Also I really doubt we are gonna see another version of MvC3 with Capcom working on SFvT and 3SOE.
