Hrmm, to start, you really screwed up your list. First of all, lets assume you are referencing JRPGs, which have very little in comon with WRPGs. If we are talking WRPGs, then no, absolutely not. The Wii won't have anywhere near the most. If we are talking JRPGs, then yes, it will, and it already does. Here is an actual list of JRPGs annoucned for the next gen systems right now:
Wii
Fragile: Farewell Ruins of the Moon
King's Story
Oboro Muramasa Youtouden
Mysterious Dungeon: Shiren the Wanderer 3
Tales of Symphonia: Knight of Ratatosk

Some of the above are of course hybrid games. JRPGS mixed with SRPGs etc. It's also worth noting that although the Wii has more, the PS3 has mroe high budget games. This is sort of interesting, because high budget JRPGS (Final Fantasy) are going to be separated from low budget RPGs (Tales of) for the first time ever.
There are of course a few high budget Wii RPGs like Monster Hunter 3, and there will be more in the future, but what it's mostly geting are what we in the western world call niche RPGs. This isn't a bad thing. There are a lot more niche JRPGs than mainstream ones, and it's unsurprising that the Wii is dominating in this field.
Most JRPGs can't afford to take the risks that the PS3 and 360 represent. Making an RPG on an HD console is a very expensive gamble. Franchises like Tales rarely break a million, and stand no chance of making a profit on the PS3 or Xbox 360. Of course, there will still be some of these games because Microsoft and Sony buy games, but there is a reason that the Wii took over the most RPGs list in such a short time.
People like to throw around the word "hardcore RPG gamer," and tag it with Final Fantasy, but Final Fantasy and the Square Enix main properties are the most casual of RPGs on the market. Mainstream RPGs are for casual gamers. The hardcore RPG gamers are the people playing Shin Megami Tensei, Baten Kaitos, and Tales.
So, in conclusion, the Wii won't be the console of Final Fantasy, but it will be the console of hardcore JRPG fans, who play more than just the mainstream games.
PS: The actual console of JRPGs is the DS, which has a release list that makes the PS2 and SNES look like jokes.
