With Germany's rather poor defence (Lahm isn't enough to redeem it), and Schweinsteiger possibly out injured, I reckon England actually have a decent chance of winning it. And, with the confidence boost of beating the team identified as England's nemesis, I reckon we'd be able to possibly get to the semis off the confidence surge.
I'm certain Germany will score, but if Rooney is in the form the training ground rumours suggest, and Defoe keeps attacking (the German backline is too slow to cope, unless Lahm and Boetang, if he starts, stay back to help the center backs out) we can outscore them. I'd probably rather see Lennon play though, I don't think Milner is effective at all against better teams, so at least with Lennon's pace we could cause them a problem and keep one of their fullbacks pinned back for the game.
We just need to hope our dysfunctional midfield comes together. Hopefully Gerrard can discover some discipline and not entirely negate Lampard like he usually does (Gerrard looks good but at the expense of the team's shape, which we cannot afford to lose at this level).
