Is there a clue to GTA 6 in GTA: San Andreas - The Definitive Edition?

Grand Theft Auto fans are desperate for any sign of a mainline extension to the GTA series. GTA 5 was released back in 2013 and Rockstar has kept mum about the release of GTA 6. However, the company did recently release GTA: The Trilogy - Definitive Edition. Now though, gamers think they may have come across the first reference to GTA 6 in the definitive edition of GTA: San Andreas.

GTA 6 reference in GTA: San Andreas - Definitive Edition?

Another #GTATrilogy mystery hunt. The Lil' Probe'Inn has an unidentified house amongst the UFO photo display... GTAVI? (jk) (or am I, where is this from?)
