Red Fly Studios is unproven, true, but they appear to be highly talented. They're also committed to the Wii, as is seen by the work they've done so far on Mushroom Men.
With that in mind, and with sales of PS2 software waning in favor of the current generation, it seems extremely likely that the Wii version will be the primary SKU, with the PS2 and DS versions being scaled-down ports.
In other words, don't worry so much. :)
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
