Its all rumours to start with,especially CvsS
going on mvs,
CvsS may not be released cos from a business standpoint the game isnt new,arcade operators will already have the original capcom one so whether they lash out £800+ for a mvs cart for any mvs cab they may have is questionable,i think samurai shodown 5 and KOF 2001 will take in the most money and this is what arcade operators will most certainly pay for.
Dont know about metal slug 4 or MOTW 2 if you have heard about these its rumours,snk are getting slower at releasing stuff so you hear about it as a rumour today and it may be a year before you see or hear anymore about it.Best just to bide your time as there is no way people can just come up with new news at the click of a finger.
