I suspect not as they're both entirely different in every aspect. Mania has a team behind it that has experince in what they're doing and every demo or clip shown has had a positive response. Valkyria Revolution was created with a new direction and the response to that was mixed from the word go and once out in Japan, it wasn't a hit.
To me, this seems like Sega knew it wouldn't do well and they've just sort of thrown it out there to die. It's been released with no fanfare, just after E3 and during a Steam sale. Conbine that with the reviews and we're looking at a game that won't sell well at all. I give Sega credit for trying something new, but again they've got the balance between being creative and building on a games already made foundations wrong.
Hopefully we'll see more of the Valkyria universe in a Chronicles style of gameplay, but we'll have to see.
