Bad, but from an accounting standpoint, somewhat superficial. Goodwill isn't cash based and is something of a measure of corporate standing (doubtless the writedown can be attributed to FFXIV). They don't actually lose 100 million in cash by writing it down.
55 mil to cancel projects and tighten standards sounds a little high so there's probably some sunk costs in there, and yes, if it means a few less travesties released, it could be better in the long run.
Still, this does explain the deluge of PSN releases, and I hope the trend contiues. Saddly they're running low (and until PSN is back it's moot anyway.) I don't think Square has much in the way of big releases in the forseeable future, just the ever delayed FF vs. XIII and XIII-2. Also with the PSP market dried up, they've lost a dominat segmant until the NPG is out and had time to entrench.
Big picture is Square needs FFXV to be beyond excelent. Lose the experimental gimick interfaces, call Bioware to write it if you have to, just produce a good RPG.
Short term cash flow ideas:
Get the rest of the PS1 library on PSN. When it's out I promise I'll buy all the ones I don't have portable versions of already.
Chrono Trigger PSP release in the vein of the FFIV complete collection. (For that matter, FFVI complete collection)
SNES Games: even without resorations, I think there'd be demand for Secret of Mana on something, and FF mystic quest would sell for nostalgia. Then there's always been a niche demand for Seikan Densetsu 3 in you'd translate the thing.
HD collections being the rage these days, let's talk FFX and Kingdom hearts.
Dissidia PS3 online: drop the story mode, add a few dozen characters from various francises, and sell a fun PS3 online party fighting game (again, once PSN is back)
If a full remake of FF7 is out, can we at least get a graphical polish on PSP, or a 3D round on the 3DS?
The above appies to things from the Taito and Eidos brands you've recently assimilated as well. You bought 'em, don't let 'em fester.
