That would be insulting our intelligence.
They would release DLC at 1000 MS points.
Then 5 months later they'll release Soul Calibur Broken Destiny The Arcade.
Charge arcades like $10,000 per cab.
Then 4 months later they annouce the Console Port of SCBDTA.
With new costume parts and guest characters.
And charge you $60 for the console port.
Then 2 months later they announce SC5.
I doubt Soul Calibur:BD will have an arcade variation, considering its on PSP. The biggest reason to play an arcade version is to play other people in person, people who are usually complete strangers. Since you can't bring your PS3/360 around, nor do you want to invite random people to your home for games, an arcade solution is the best one. Bring in the PSP version, and you have introduced a public method to play the game against others using the Ad Hoc feature. An Arcade version would only then provide access to those who don't have a PSP/BD, however those people will most likely get their asses handed to them by the people who have been practicing like mad on the PSP version, learning all the differences. In the end, those people will not want to play against you and your stuck with people on PSP's.
There will be some people who are exceptions - those who have the PS3/360 version and are very good & they do not own a PSP. However, their market share would be so small, that the profit from catering to them would only result in a loss.
Arcades generally only serve 2 major purposes - Public Multiplayer Gatherings and Early Game Access (Pre-Console release). Sort of like seeing a movie before its out on DVD/BD. Cut out early access & Public gathering function, and they are worthless.
Even if they did release an arcade version, releasing the "port" of the arcade version wouldn't sell very well. You would effectively be handing over the 3 SW characters for 3 new characters (Kratos, Dampierre, and maybe one more). And there would be issues then to release it on the 360, due to Kratos.
The only reasonable route they will take is the following
Release Broken
3-4 Months
Release Broken DLC to Console versions (excluding Kratos from 360 version)
3-4 Months
Announce SC5
Release Maid Pack 666 for SC4.
