Niko headed to San Andreas?

When you finish the Grand Theft Auto IV storyline, you get access to ‘The Story Gang’ within Rockstar’s Social Club if you move around tall the papers you’ll see a plane ticket on Air Sol.

The ticket reads:

From: Liberty City
To: San Andreas

MR Niko Bellic

If you remember from Grand Theft Auto III, there were billboards that read “See you in Vice City” which apparently foreshadowed where the series was going next. Is this the same?
