Rumors pertaining to the PSP2 (sometimes called PSP-4000) seem to be getting wilder and more exciting as the days go by. First, we heard about the UMD drive's removal and the addition of sliding screens, but now it's all touch screens (that slide) and dual analog nubs. According to PocketGamer, who apparently spoke with a developer working on the new hardware (and not Dave Perry), all of these new features will be available later this year when the PSP2 ships sometime before Christmas.
If we're following Sony's usual timeline of events, we'll see the new hardware unveiled at E3 -- just like the PSP-2000 and PSP-3000 in the previous years.
Nearest Light 2.0 has been completed. This vorisen has an improved setup that will download the monthly update directly from USCG for the region of interest (the previous file method is still supported). In addition, there is a Print Table button on the Light List tab so that a list can be pre-printed for the area to be surveyed in a Cooperative Charting event. The old vorisen is still listed above but will be removed if the preference is for the new vorisen.
