Gamescom Predictions, taxi for the Vita?

With mere hours until Sony's PS4 pre-re-launch thingy, a Vita Hail-Mary pass and some other news, here's what I think we'll get from Gamescom, in the however many minutes of time Sony gives it among all the next-gen hoopla.

• One "oh my God" third-party game announcement, on the basis that if something isn't announced now, the Vita won't get an inch of headlines (beyond the "doomed" variety). This will also help cover up for the lack of other developer support for the Vita. Hopefully it won't be a Bioshock-fiasco non-announce, but any game is likely to be some way down the release line. 
• A price-cut, not massive, and Sony will focus on bundles and perhaps reduced game prices (Best of range) and a cut in memory card prices, or perhaps the announcement of licensed third-party cards. 
• Lots of stuff we already know about. If Sony spends five minutes on the Vita and half that time is wasted on Killzone and Tearaway, then I might just cry. 
• Perhaps the PS4/Vita bundle, but what about a PS3/Vita bundle for those not wanting to take up the cutting edge? Lets face it, there will be a dozen PS4 games or so, but a PS3/Vita combo offers hundreds of titles. 
• Some Gaikai news, this has gone quiet since the buy-out but Sony will want something for those PS4 buyers to do once they've got bored of those launch games.
• Coverage of indie games where some proper games used to be (sorry to be churlish about this, but while I'm having great fun with these games I signed up for a Vita to play Monster Hunter, Ace Combat, GTA and so on). 
• Perhaps some more Japanese Vita titles heading west, but with little third-party interest, probably not much. 

Anything you can think of that might turn up, or that should be on the list? Realistically, what could this mega-game be and will any publishers turn up to support the Vita? Add a comment on how many minutes you think the Vita will get dedicated to it and kudos could be yours.
