As reported in MCV Capcom have openly admitted to the outcry over several (12 in fact) have been set aside from the upcoming beat'em: Street Fighter X Tekken for DLC. However what has really put noses out of joint is that those 12 characters are really just locked on-disc content. So when the character packs become available, all your paying for is a unlock code that allows you access to content that's on the disc you already paid for. Capcom's explanation was
"The character information and files were intentionally included on retail versions of the PS3 and Xbox 360 game to save hard drive space and to ensure for a smooth transition when the DLC is available, allowing players who choose not to purchase the content the ability to play against players that did"
Even though they're avoiding the whole point of the outcry, in that how can they knowingly lock content you have paid for and then sell it back to you under the guise of extra content. If you own Marvel vs Capcom 3, then this probably won't be much of a shock to you. You only had to notice how small the downloads were for Shuma Gorath and Jill Valentine were, to see they were unlock codes too. Because that's what capcom does, be it making you pay for a verses mode in Resident Evil 5 or charging a few quid for palette swaps for the costumes on Street Fighter 3: Third Strike (which can only be viewed by your opponent if they were stupid enough to buy the costume pack as well) their business model is to whip the horse until it dies. The horse, in this case, being your wallet.
