With some exceptions, it seems most of the pro Japanese players came around to Deathsmiles. SWY, ISO, TAC, Dame K.K., tsumanne, etc. They all love the game (TAC mentions in the DVD booklet he thinks the game is brilliant). The game is so good (in terms of its scoring system, level design, etc) that even if you hate the whole loli girl character thing it's hard to dismiss it.
As for this, it's too early to tell. We'd need more info than a simple picture of two characters from a game that may or may not be an arcade game.
