Google will only be for Google sites with a few authority sites mixed in the results.

Unlikely. Web search is Google's core product, and real companies don't simply toss away their core products and risk losing their end users.

As for competing to be on the first page, that depends on where you'd rank without image, book, or other results on the SERP. If you rank #9 or #10 for a Web search on "widgets," then you're likely to end up on page 2; if you rank in the first half-dozen Web results, you'll probably still be on page 1.
