PS2 support is already being dropped, even when there's a Wii version in some cases.
On one hand no PS2 could mean 3rd parties will built to Wii specs not PS2 but more likely larger devs will continue to put their 2nd & 3rd teams on Wii and keep the 1st teams (the best ones) on HD. So Wii games will continue to be subpar from them.
Smaller devs will continue to focus on Wii only and they quality of their games will rise.
