IQ Mania & XI Colosseum PSP Puzzle Games

[The Glider]

Has anyone here bought either of these two titles for the PSP ? Being a puzzle slut, I'm very tempted, but I'm wondering about any possible language barriers & if there's a possibility that these two games will ever get a Western release. They're only about ?15-?16 on eBay so I suppose they're worth a punt at that price...
