Yeah, that WO that never made it to fruition, be it true or not , is pretty well known about at this forum.
But the more I think about it, maybe it just might of been a 'Console' version of 2048 that was being made, with different menus, but then I double think that with , well why wouldn't they have released it at the same time as the VITA version.....who knows?

I'm sure there are plenty of WO tracks and new craft in various stages of completion that nobody except those who worked on them have seen, it stands to reason given how long SL/ Psygnosis was operational.

Even the guys at R8 games, having a very small design team, have several tracks [about 6] that have yet to be seen in the full game of PACER [Formally known as Formula Fusion]....I've recorded videos when I was testing them.
