SF4 is not coming on PS4/Xbox One because there are not enough consoles sold, not enough players liking fighting games on these consoles, no crossplatform to have enough online opponents, and because arcade sticks costs 200$ and nobody wants to buy a 400$ console to play a game you can buy 30$ on steam and run on any computer bought this past 4 years.
GGXrd is crossplatform between ps3/ps4, Capcom could do the same
SF4 came out on 3DS
UMVC came out on Vita
Arcade sticks can be modded, more can be bought, convertors will be made.
Capcom ports anything that can be ported to anything that can play it. Except for PC...fuck you, Dragon's Dogma port.
None of your reasons hold weight against other games released in the market and what Capcom has done in the past.
