Those titles for PS3 and X360 were already planned 2-3 years ago so yes they will continue to get announcements of big games until it hits the point that the recent low sales became a factor in developers board rooms.
Sure, Wii is getting some quickly put together games to take advantage of the market before rivals do and to help shoulder the losses made on the bigger budget releases for the X360/PS3. EA and Ubisoft both have admitted to to doing this already.
The wait game played by Sony fans is baseless speculation that Wii will fade, PS3 will suddenly dominate, etc... The wait I'm informing you of regarding future Wii game development is a known industry cycle based on market analysis, planning and budgeting, initial development, publisher shopping (if needed) and eventually full on development. This is when you start to actually hear about the game and maybe get a screen shot or two. All a good while AFTER the decision to make the game even came to light.
